1.Introduction & The Mechanics of Grammatical Voice
Core FoundationUnderstanding the shift in discourse perspective between the agent and the receiver of an action.
What Is Voice in English Syntax?
Voice is the grammatical category that indicates the relationship between the action expressed by the verb and the participants identified by its arguments (subject and object). In Active Voice, the grammatical subject is the "agent" or "doer" of the action. In Passive Voice, the grammatical subject is the "patient" or "recipient" who undergoes the action.
- Active Focus (Agent-Centric): "The vigilance directorate investigated the tender irregularities." (Emphasizes who performed the inquiry).
- Passive Focus (Receiver-Centric): "The tender irregularities were investigated by the vigilance directorate." (Emphasizes the issue undergoing investigation).
- The Transitivity Precondition: Only transitive verbs (verbs possessing a direct object) can be converted into standard passive constructions. Intransitive verbs (e.g. arrive, sleep, die, happen) cannot form passives because there is no direct object to promote to the subject position.
Why Passive Voice Is Critical in Competitive Exams
Passive voice is the standard register of official gazettes, legal rulings, scientific reports, and administrative memoranda. Competitive exam questions (especially SSC CGL Tier 2, CDS, and NDA) test your ability to convert voice swiftly and accurately while rigorously preserving original grammatical tense and aspect.
2.The Universal Voice Conversion Formula
Formula & MechanicsThe invariant three-step structural shift: Object promotion, BE insertion, and V3 past participle.
The Invariant Voice Formula
Sentence Formations & Formulas:
Active Voice Structure:
Subject (Agent) + Finite Verb + Object (Receiver)Ex: “The magistrate [S] signed [V] the release order [O].”
Passive Voice Structure:
Object (Promoted Subject) + [Appropriate Form of BE] + V3 (Past Participle) + [by + Agent]Ex: “The release order [O] was signed [BE + V3] by the magistrate [by + S].”
The entire system of English passive transformation hinges upon a single morphological invariant: the verb BE in the tense of the active verb, followed immediately by the Past Participle (V3) of the main verb. The main lexical verb ALWAYS changes to its V3 form in passive voice.
| Active Tense / Form | Appropriate Inflection of BE | Passive Auxiliary Formula | Transformation Example |
|---|---|---|---|
| Present Simple (V1/V5) | am / is / are | am / is / are + V3 | The clerk verifies documents. → Documents are verified. |
| Past Simple (V2) | was / were | was / were + V3 | The clerk verified documents. → Documents were verified. |
| Continuous Aspects | being | is/are/was/were + being + V3 | The clerk is verifying files. → Files are being verified. |
| Perfect Aspects | been | has/have/had + been + V3 | The clerk has verified files. → Files have been verified. |
| Modals & Future (will, can, must) | be | modal + be + V3 | The clerk must verify files. → Files must be verified. |

3.Tense-by-Tense Transformation Matrix & Non-Passive Forms
Systematic GridExhaustive transformation formulas across all 8 standard passive tenses and the 4 non-passive exceptions.
The 8 Standard Tense Transformations
| Tense | Active Voice Construction | Passive Voice Construction | Natural Exam Example |
|---|---|---|---|
| Present Simple | Subject + V1/V5 + Object | Object + is/am/are + V3 + by S | The team conducts audits. → Audits are conducted by the team. |
| Present Continuous | Subject + is/am/are + V4 + Object | Object + is/am/are + being + V3 + by S | The engineer is repairing the turbine. → The turbine is being repaired. |
| Present Perfect | Subject + has/have + V3 + Object | Object + has/have + been + V3 + by S | The agency has arrested the suspect. → The suspect has been arrested. |
| Past Simple | Subject + V2 + Object | Object + was/were + V3 + by S | The council passed the ordinance. → The ordinance was passed by the council. |
| Past Continuous | Subject + was/were + V4 + Object | Object + was/were + being + V3 + by S | They were drafting the memorandum. → The memorandum was being drafted. |
| Past Perfect | Subject + had + V3 + Object | Object + had + been + V3 + by S | The jury had delivered the verdict. → The verdict had been delivered. |
| Future Simple | Subject + will/shall + V1 + Object | Object + will/shall + be + V3 + by S | The ministry will sanction the grant. → The grant will be sanctioned. |
| Future Perfect | Subject + will/shall + have + V3 + Object | Object + will/shall + have been + V3 + by S | We will have finished the audit. → The audit will have been finished. |

The 4 Non-Passive Forms in Standard Examination English
In standard competitive-examination English, 4 tense-aspect combinations are strictly considered non-passive: (1) Present Perfect Continuous, (2) Past Perfect Continuous, (3) Future Continuous, and (4) Future Perfect Continuous. Sentences like "The project has been being executed" are avoided due to awkward phonetic clustering ("been being"). In exam questions offering choices, select "No passive voice possible" or the alternative rephrased active construction.
4.Modal Auxiliaries in Passive Voice
ModalsFormulas for simple modals and modal perfect past deductions/counterfactuals.
Simple Modals vs. Modal Perfect Passives
Sentence Formations & Formulas:
Simple Modal Passive Formula:
Subject + Modal + V1 + Object → Object + Modal + BE + V3 + (by Subject)Ex: “You must submit the affidavit. → The affidavit must be submitted.”
Modal Perfect Passive Formula:
Subject + Modal + have + V3 + Object → Object + Modal + HAVE BEEN + V3 + (by Subject)Ex: “They should have notified the board. → The board should have been notified.”
The classified report could not be accessed by unauthorized staff.
The classified report could not be access by unauthorized staff.
Analysis: Modal passives strictly demand "be + V3" (be accessed), never a base verb.
The tragic railway derailment might have been averted by timely signaling.
The tragic railway derailment might have averted by timely signaling.
Analysis: Omitting "been" renders the sentence active, implying the derailment averted something else.
5.Imperative Sentences, Commands, Advice & Requests
High YieldConverting sentences without overt grammatical subjects using "Let", "Should be", and "You are requested".
Four Standard Imperative Passive Paradigms
| Imperative Nature | Active Construction | Standard Passive Formula | Natural Exam Example |
|---|---|---|---|
| Direct Order / Command | V1 + Object: "Shut the main gate." | Let + Object + be + V3 | Let the main gate be shut. |
| Moral Duty / Advice | V1 + Object: "Respect the elders." | Object + should be + V3 | The elders should be respected. |
| Polite Request | Please / Kindly + V1 + Object: "Please sign here." | You are requested to + V1 | You are requested to sign here. |
| Negative Prohibition | Do not + V1 + Object: "Do not touch the wire." | Let + Object + not be + V3 (or: You are forbidden to...) | Let the wire not be touched. / You are forbidden to touch the wire. |
← Scroll horizontally to view full table →
Distinguishing Orders from Advice
Examiners often test your discernment between commands and moral duties. For commercial/executive orders ("Dispatch the summons immediately"), "Let the summons be dispatched immediately" is preferred. For moral/ethical guidance ("Help the indigent"), "The indigent should be helped" is the accurate standard option.
6.Interrogative Sentence Transformations
Exam ClassicsConverting Yes/No and Wh- questions while preserving inverted interrogative syntax.
Yes/No Questions & Auxiliary Restructuring
When converting questions, the sentence must remain a question. The auxiliary verb precedes the new subject.
Did the superintendent approve the revised roster? → Was the revised roster approved by the superintendent?
Did the superintendent approve the revised roster? → The revised roster was approved by the superintendent?
Analysis: The converted sentence must retain question syntax (Auxiliary + Subject + V3).
Have they completed the forensic audit? → Has the forensic audit been completed by them?
Have they completed the forensic audit? → Have the forensic audit been completed by them?
Analysis: The auxiliary changes from plural "Have" to singular "Has" to match singular "audit".
Wh- Questions: "Who" and "Whom" Transformations
Sentence Formations & Formulas:
"Who" into "By whom":
Who + Verb + Object? → By whom + Auxiliary + Promoted Subject + V3?Ex: “Who authored this thesis? → By whom was this thesis authored? (or: Who was this thesis authored by?)”
"Whom" into "Who":
Whom + Auxiliary + Subject + Verb? → Who + Auxiliary + V3 + by + Subject?Ex: “Whom did the committee select? → Who was selected by the committee?”
Modern Exam Trend: End Preposition
While traditional competitive exams heavily favor "By whom was this written?", modern exams (SSC CGL Tier 2) also accept "Who was this written by?". Both represent valid passive forms of the interrogative.
7.Complex Predicates: Two Objects, Prepositions & Non-Finites
Advanced NuanceDitransitive verbs, retained dependent prepositions, and non-finite complement passives.
Verbs with Two Objects (Direct vs. Indirect)
Ditransitive verbs (give, award, grant, offer, lend, send) possess two objects: an Indirect Object (typically a person) and a Direct Object (typically a thing). Either object can become the subject in the passive voice, but promoting the Indirect Object (the person) is widely preferred in standard English.
Active: The Governor awarded Dr. Sen a gold medal.
Passive 1 (Indirect Object Promoted - Preferred): Dr. Sen was awarded a gold medal by the Governor.
Passive 2 (Direct Object Promoted): A gold medal was awarded to Dr. Sen by the Governor.
Analysis: When the Direct Object is promoted, the preposition "to" or "for" must precede the person.
Verbs with Fixed Dependent Prepositions
When a transitive phrasal verb or verb with a fixed dependent preposition (e.g. laugh at, look into, rely upon, object to) is converted into passive voice, the preposition MUST NOT be dropped. It remains bonded to the past participle V3.
The special branch is looking into the espionage allegations. → The espionage allegations are being looked into by the special branch.
The espionage allegations are being looked by the special branch.
Analysis: Dropping "into" completely corrupts the meaning of the phrasal verb.
The senior officers laughed at his innovative proposal. → His innovative proposal was laughed at by the senior officers.
His innovative proposal was laughed by the senior officers.
Analysis: "At" must remain attached to "laughed".
Perception Verbs and Bare Infinitives
In active voice, verbs of perception (see, hear, watch, notice) and the causative "make" take a bare infinitive without "to". However, when converted to passive voice, the bare infinitive MUST expand into a full to-infinitive.
Active: I saw him enter the prohibited zone.
Passive: He was seen to enter the prohibited zone.
He was seen enter the prohibited zone.
Analysis: In passive voice, "enter" must take the to-infinitive marker ("to enter").
Active: The interrogator made the suspect confess.
Passive: The suspect was made to confess by the interrogator.
The suspect was made confess by the interrogator.
Analysis: "Made" requires a to-infinitive in passive voice.
8.The Agent "By" Phrase & Alternate Prepositions
High YieldKnowing when to omit the agent and identifying participles that reject the preposition "by".
When to Omit the Agent Phrase
- Indefinite or Vague Agents: When the agent is "someone", "somebody", "nobody", "people", or "they", the "by..." phrase is normally omitted: "Someone has stolen my identity credentials" → "My identity credentials have been stolen."
- Obvious Agents: When the agent is implicit in the verb: "The police apprehended the fugitive" → "The fugitive was apprehended" (mentioning "by the police" is redundant).
- Focus on Result: When the doer is unimportant compared to the outcome: "The highway was inaugurated yesterday."
Participles Governing Prepositions Other than "By"
Not all passive verbs take the preposition "by". Certain psychological, sensory, and state verbs demand specific dependent prepositions. Using "by" with these verbs is an immediate error in competitive examinations.
| Verb | Mandatory Preposition | Incorrect with "By" | Correct Exam Construction |
|---|---|---|---|
| know | to | He is known by me. ❌ | He is known to me. ✅ |
| marry | to | She was married by Rohit. ❌ | She was married to Rohit. ✅ |
| surprise | at | I was surprised by his conduct. ❌ | I was surprised at his conduct. ✅ |
| satisfy | with | We were satisfied by the report. ❌ | We were satisfied with the report. ✅ |
| contain | in | The jar is contained by honey. ❌ | Honey is contained in the jar. ✅ |
| annoy | with (person) / at (thing) | He was annoyed by his clerk. ❌ | He was annoyed with his clerk. ✅ / annoyed at his insolence. ✅ |
| please | with | The jury was pleased by his humility. ❌ | The jury was pleased with his humility. ✅ |

9.Quasi-Passive Verbs & Middle Voice
NuanceActive syntactic forms that convey passive semantic meanings.
Active Form with Passive Meaning
Sentence Formations & Formulas:
Quasi-Passive Conversion Formula:
Subject + Verb + Adjective → Subject + is/are + Adjective + WHEN + it is / they are + V3Ex: “Quinine tastes bitter. → Quinine is bitter when it is tasted.”
Quasi-passive (or middle-voice) verbs are grammatically active in morphology but passive in sense. In competitive examinations, they are converted into passive constructions using a conditional or temporal clause introduced by "when it is / when they are".
This fabric feels soft. → This fabric is soft when it is felt.
This fabric is felt soft.
Analysis: Standard examination format requires the expanded conditional clause.
These Kashmiri apples smell sweet. → These Kashmiri apples are sweet when they are smelled.
These Kashmiri apples are smelled sweet.
Analysis: The property (sweet) is observed upon sensory examination (when smelled).
10.10 High-Frequency Exam Error Patterns & Corrections
Exam DiagnosticsAnalytical deconstruction of the 10 most pervasive voice transformation errors.
1. Altering Tense Instead of Preserving It
Active: She wrote an article. → Passive: An article was written by her.
Active: She wrote an article. → Passive: An article has been written by her.
Analysis: Voice changes perspective, NOT tense. Past simple ("wrote") must convert to past simple passive ("was written"), not present perfect.
2. Omitting "Being" in Continuous Aspects
The technicians are repairing the bridge. → The bridge is being repaired by the technicians.
The technicians are repairing the bridge. → The bridge is repaired by the technicians.
Analysis: Omitting "being" turns a continuous action into a simple present habit.
3. Dropping Fixed Dependent Prepositions
They laughed at the vagrant. → The vagrant was laughed at by them.
They laughed at the vagrant. → The vagrant was laughed by them.
Analysis: The preposition "at" is integral to the phrasal meaning and must be retained.
4. Using "By" Instead of "To" with "Known"
His philanthropic deeds are known to everyone.
His philanthropic deeds are known by everyone.
Analysis: "Known" governs the preposition "to", never "by".
5. Omitting "Been" in Perfect Tense Passives
The authorities have inspected the warehouse. → The warehouse has been inspected by the authorities.
The authorities have inspected the warehouse. → The warehouse has inspected by the authorities.
Analysis: Without "been", "has inspected" remains active, implying the warehouse did the inspecting.
6. Retaining Bare Infinitive after Passive "Make"
The officer was made to sign the confession.
The officer was made sign the confession.
Analysis: Passive "made" mandates a full to-infinitive ("to sign").
7. Reversing Interrogative Inversion in Questions
Why did you breach the security cordon? → Why was the security cordon breached by you?
Why did you breach the security cordon? → Why the security cordon was breached by you?
Analysis: Questions must maintain auxiliary-subject inversion ("was the security cordon breached").
8. Using "By whom" with Incorrect Auxiliary Position
Who broke the glassware? → By whom was the glassware broken?
Who broke the glassware? → By whom the glassware was broken?
Analysis: The auxiliary "was" must precede the subject "the glassware" in interrogatives.
9. Attempting Passive on Intransitive Verbs
The accident happened late last night.
The accident was happened late last night.
Analysis: "Happen" is intransitive; it has no direct object and cannot be made passive.
10. Using Base Verb Instead of V3 in Modal Passives
The dispute must be resolved amicably.
The dispute must be resolve amicably.
Analysis: All passives require the past participle V3 ("resolved"), never the base stem.
11.Master10 6-Step Voice Diagnostic Chain & Quick Revision Matrix
Algorithm & SummaryA fail-safe algorithmic elimination procedure for voice MCQs and an exhaustive conversion table.
The Master10 6-Step Voice Diagnostic Algorithm
Sentence Formations & Formulas:
Step 1: Isolate Subject, Verb, and Object:
Verify that the verb is transitive. Locate the direct object that will become the new subject.Ex: “"The superintendent [S] has reviewed [V] the file [O]."”
Step 2: Lock the Tense and Aspect:
Identify the active tense. The passive auxiliary MUST match this tense exactly.Ex: “"has reviewed" = Present Perfect → Passive auxiliary must be "has/have been".”
Step 3: Harmonize Number Concord with the New Subject:
Ensure the auxiliary matches the number of the promoted subject.Ex: “"The file" is singular → "has been", not "have been".”
Step 4: Check Continuous Marker ("Being") or Perfect Marker ("Been"):
Continuous → must have "being"; Perfect → must have "been".Ex: “"The file has been reviewed".”
Step 5: Check Preposition Retention and Particle Idioms:
Retain phrasal prepositions (laughed at); verify non-"by" prepositions (known to, surprised at).Ex: “"known to", not "known by".”
Step 6: Maintain Sentence Polarity & Type:
Statements stay statements; questions stay inverted questions; commands stay imperatives.Ex: “"Was the file reviewed?" (not "The file was reviewed?").”
