In short: A phrasal verb is a multi-word verb formed by combining a base verb with one or two particles, such as an adverb or a preposition. The resulting phrase has an idiomatic meaning different from the individual words, as seen in 'call off' (cancel), 'give up' (quit), and 'look forward to' (anticipate).
When you look at the words 'give' and 'up' separately, each carries a familiar dictionary meaning. Put them together, however, and 'give up' no longer refers to handing something upward; it means to surrender or stop trying. Combinations like this are phrasal verbs, and they form an essential part of natural English.
For students in Class 5 to 12 across CBSE, ICSE, and IGCSE curricula, phrasal verbs appear regularly in cloze tests, sentence transformations, and essays. Understanding how these verbs function, which ones split around objects, and how to use correct word order helps you write with precision and secure top marks in school examinations.
What a phrasal verb is and how it functions
A phrasal verb pairs a standard verb with one or two particles, usually adverbs or prepositions such as 'off', 'in', 'out', 'up', or 'down'. The combination acts as a single grammatical unit.
Its defining quality is idiomatic meaning. In literal combinations, words keep direct physical senses, such as walking up a staircase. In a phrasal verb like 'bring up', the words unite to mean raise a child or introduce a topic.
- Base verb: the action word that inflects for tense.
- Particle: an adverb or preposition altering core meaning.
- Idiomatic unit: the combined phrase functions as a single verb.
| Combination | Literal meaning | Phrasal meaning | Original example sentence |
|---|---|---|---|
| Look up | Direct eyes upward | Search for information | Sunita looked up the difficult word in her glossary. |
| Run into | Collide with an object | Meet unexpectedly | While crossing the bazaar, Dev ran into his former tutor. |
| Turn down | Bend downward | Decline an offer | The captain turned down the invitation owing to tests. |
| Take off | Remove an item | Begin flight | The flight took off smoothly despite morning fog. |
Transitive and intransitive phrasal verbs
Phrasal verbs divide into transitive and intransitive categories based on direct objects. Recognising this difference ensures clauses are grammatically complete.
Transitive phrasal verbs require an object: saying 'the monitor turned off' leaves listeners waiting, while adding 'the projector' completes the thought. Intransitive phrasal verbs need no object, describing complete actions such as waking up or breaking down.
- Transitive: requires an object answering 'what?' or 'whom?'.
- Intransitive: completes its action without an object.
- Dual verbs: context decides whether an object is needed.
| Category | Object rule | Phrasal verb | Original example sentence |
|---|---|---|---|
| Transitive | Requires object | Call off (cancel) | The committee called off the badminton match. |
| Transitive | Requires object | Back up (save) | Priya backed up her project files on a drive. |
| Intransitive | No object | Break down (fail) | The school bus broke down near the junction. |
| Intransitive | No object | Show up (arrive) | Thirty parents showed up for the orientation session. |
Separable and inseparable phrasal verbs
Transitive phrasal verbs follow strict word order. In separable verbs, base verb and particle may stay together or separate around a noun: 'turn off the lamp' and 'turn the lamp off' are both correct.
However, examiners regularly test pronoun placement. When the direct object is a pronoun like 'it' or 'them', a separable verb must split: write 'turn it off', never 'turn off it'. Inseparable phrasal verbs never allow an object to divide the parts.
- Separable with noun: the noun sits before or after the particle.
- Separable with pronoun: the pronoun must split the verb and particle.
- Inseparable: the object always follows the particle.
| Type | Noun placement | Pronoun placement | Original example sentence |
|---|---|---|---|
| Separable | Before or after particle | Between parts only | The prefect handed the sheets out before the bell. |
| Separable | Before or after particle | Between parts only | Kunal switched the computer off after saving his file. |
| Inseparable | After particle only | After particle only | Ananya came across an old coin in her family trunk. |
| Inseparable | After particle only | After particle only | The bowler takes after his uncle in his delivery style. |
Three-part phrasal verbs with two particles
Three-part phrasal verbs combine a base verb with an adverb particle and a preposition. Also called phrasal-prepositional verbs, they include expressions like 'look forward to' and 'put up with'.
These verbs follow two rules. First, they are always transitive because the final preposition requires an object. Second, they are strictly inseparable: the object must follow the preposition. Following verbs must take the gerund (-ing) form.
- Structure: base verb plus adverb particle plus preposition.
- Inseparability: never insert words between components.
- Gerund pattern: following verbs must end in '-ing'.
| Three-part verb | Exact meaning | Key grammar rule | Original example sentence |
|---|---|---|---|
| Look forward to | Anticipate with pleasure | Requires noun or gerund | The pupils look forward to visiting the museum. |
| Put up with | Tolerate or endure | Strictly inseparable | The warden refused to put up with rowdy conduct. |
| Run out of | Exhaust available stock | Preposition required | The lab ran out of litmus paper during the test. |
| Cut down on | Reduce consumption | Object follows 'on' | The coach advised the squad to cut down on soda. |
How particles alter the meaning of base verbs
Secondary pupils often find phrasal verbs demanding because one base verb forms multiple meanings when paired with different particles. Observing regular particle meanings helps you understand new combinations.
For example, 'off' often indicates departure or cancellation, as seen in 'take off' and 'call off'. The particle 'up' frequently signals completion or arrival, as in 'drink up' and 'turn up'. These patterns help you deduce unfamiliar meanings in reading passages.
- Particle 'off': signifies separation, departure, or cancellation.
- Particle 'up': denotes completeness, intensification, or arrival.
- Particle 'out': implies outward motion, distribution, or extinction.
- Particle 'down': denotes reduction, decline, or recording on paper.
| Root verb | Phrasal verb | Meaning | Original example sentence |
|---|---|---|---|
| Look | Look into | Investigate formally | The committee agreed to look into the canteen complaints. |
| Look | Look up to | Admire or respect | Junior athletes naturally look up to the senior champion. |
| Put | Put off | Postpone or delay | The council decided to put off the debate until next month. |
| Put | Put out | Extinguish a flame | The caretaker used sand to put out the small chemical flame. |
| Break | Break out | Erupt suddenly | A sudden flu outbreak broke out across several hostels. |
Register and tone: choosing between phrasal verbs and formal verbs
In examinations across CBSE, ICSE, and IGCSE, marks depend on maintaining appropriate register. Phrasal verbs are natural and idiomatic, making them suitable for conversations, informal letters, and narratives.
In formal tasks like letters to principals and analytical essays, phrasal verbs can sound overly casual. Formal English prefers single verbs derived from Latin roots. Learning to replace phrasal verbs with formal equivalents is an essential skill.
- Informal writing: phrasal verbs add authentic rhythm to narratives and dialogue.
- Formal writing: single Latinate verbs ensure precision and serious tone.
- Tense alignment: always conjugate the formal replacement in the same tense.
| Phrasal verb | Formal equivalent | Contextual register | Original example sentence |
|---|---|---|---|
| Call off | Cancel | Official letter | The authorities decided to cancel the annual parade. |
| Look into | Investigate | Formal report | The inspector promised to investigate the warehouse leakage. |
| Put off | Postpone | Academic notice | The school chose to postpone the practical examinations. |
| Give up | Abandon | Analytical essay | The explorer refused to abandon the expedition. |
| Turn down | Decline | Official letter | The panel had to decline late applications. |
Step-by-step method to analyse phrasal verbs in sentences
When analysing phrasal verbs in cloze tests or sentence transformation exercises, following a systematic method prevents errors and ensures full marks.
First, check whether the phrase is idiomatic or literal. Next, determine whether the verb requires an object. If transitive, identify whether it is separable or inseparable. Then check pronoun placement, ensuring pronouns split separable verbs. Finally, confirm that tense changes apply only to the base verb.
- Step 1: Determine whether the phrase is idiomatic or literal.
- Step 2: Check transitivity by asking 'what?' or 'whom?'.
- Step 3: Test separability using standard word order rules.
- Step 4: Verify that pronouns split separable phrasal verbs.
- Step 5: Ensure tense inflection applies only to the base verb.
| Sentence under analysis | Meaning check | Transitivity | Separability | Pronoun rule |
|---|---|---|---|---|
| Meera threw away the outdated notes. | Idiomatic (discarded) | Transitive (object: notes) | Separable | Becomes 'threw them away' |
| The flight touched down on schedule. | Idiomatic (landed) | Intransitive (no object) | Inseparable | Pronoun rule not applicable |
| Aarav takes after his grandfather. | Idiomatic (resembles) | Transitive (object: grandfather) | Inseparable | Remains 'takes after him' |
| We must cut down on paper waste. | Idiomatic (reduce) | Transitive (three-part verb) | Inseparable | Object follows 'on': 'cut down on it' |
Common mistakes
| Wrong | Right | Why |
|---|---|---|
| Please turn off it before leaving the laboratory. | Please turn it off before leaving the laboratory. | When the object of a separable phrasal verb is a pronoun like 'it' or 'them', the pronoun must sit between the base verb and particle. |
| Rohit takes his grandfather after in temperament. | Rohit takes after his grandfather in temperament. | The phrasal verb 'take after' is inseparable. Its direct object must follow the prepositional particle rather than splitting the verb. |
| The students look forward to meet the author. | The students look forward to meeting the author. | In 'look forward to', 'to' is a preposition. Prepositions must be followed by a noun or a gerund ending in '-ing'. |
| The inspector decided to investigate into the theft. | The inspector decided to investigate the theft. | Students confuse 'investigate' with 'look into'. The single verb 'investigate' takes a direct object without the preposition 'into'. |
| The canteen has run out drinking water today. | The canteen has run out of drinking water today. | Three-part phrasal verbs require all their particles. Dropping 'of' from 'run out of' produces an incomplete clause. |
| The clock broke down and winded up in scrap. | The clock broke down and wound up in scrap. | Only the base verb inflects for tense. The past tense of the irregular verb 'wind up' is 'wound up', not 'winded up'. |
Exam tips
- In cloze passages, verify whether the blank requires an adverb particle like 'away' or a preposition like 'into'; examiners test paired particles that alter meanings.
- When replacing a noun with a personal pronoun in transformations, always check separability; pronouns like 'it' or 'them' must sit between verb and particle.
- When changing sentences to passive voice, retain the phrasal verb's particle; write 'The meeting was called off by the headmaster', keeping 'off' with the verb.
- Ensure tense inflection applies strictly to the base verb while keeping particles in uninflected forms; write 'carried out' or 'ran into' for past events.
- In formal letters to principals, editor letters, and factual reports, substitute casual phrasal verbs with formal single verbs, writing 'postpone' rather than 'put off'.
Practice questions
Try each one, then open the answer.
- Identify the phrasal verb and state whether it is transitive or intransitive: 'The fire alarm went off during assembly.'
Answer
'Went off' is intransitive; it takes no direct object. - Rewrite by replacing the noun phrase with 'them': 'Kavita handed out the revision worksheets.'
Answer
'Kavita handed them out.' A pronoun object must split a separable phrasal verb. - Correct the error: 'The teacher asked us to look forward to complete the project file.'
Answer
'The teacher asked us to look forward to completing the project file.' The preposition 'to' requires a gerund. - Replace the word in brackets with a phrasal verb: 'The committee decided to [cancel] the festival.'
Answer
'Call off'. The sentence becomes: 'The committee decided to call off the festival.' - Replace the phrasal verb with a formal single verb: 'The board promised to look into the complaints.'
Answer
'Investigate'. The revised sentence is: 'The board promised to investigate the complaints.' - Classify this phrasal verb as separable or inseparable: 'The detective ran into her teacher.'
Answer
Inseparable. The direct object 'her teacher' cannot split 'ran' and 'into'. - Fill in the blank: 'Firefighters managed to put ______ the blaze before midnight.' (off / out / down)
Answer
'Out'. 'Put out' means extinguish, while 'put off' means postpone. - Identify and correct the error: 'The science club has run out charts for the exhibition.'
Answer
Add 'of'. The correct sentence is: 'The science club has run out of charts for the exhibition.' - Rewrite in the passive voice: 'The council called off the afternoon debate session.'
Answer
'The afternoon debate session was called off by the council.' The particle 'off' stays with 'called'. - Choose the correct past tense: 'The clock finally (winded up / wound up) in the museum.'
Answer
'Wound up'. The irregular base verb 'wind' forms its simple past as 'wound'.
