What is a phrasal verb? A guide for English language teachers

If you are new to teaching, or about to start a CELTA course, you may have come across the term phrasal verb and wondered what it means. You may also have heard learners say, “English has too many phrasal verbs,” without being entirely sure how to respond. This guide explains what a phrasal verb is, why learners find them difficult, and how you can approach them in the classroom with clarity and confidence.

What is a phrasal verb?

A phrasal verb is a verb combined with a particle. The particle is an adverb or a preposition.

Examples include:

• wake up

• turn off

• look after

• run out of

The meaning of the whole unit differs from the meaning of the base verb on its own. Turn off means switch something off. Run out of means have no more of something. In both cases, the verb and particle together create a new lexical item with a new meaning.

It is useful to distinguish phrasal verbs from other multi-word phrases and from idioms. In look at the board, the verb keeps its core meaning and so it's not considered a phrasal verb. In look after a child, the meaning changes to “take care of,” so the unit behaves as a single item of vocabulary and this is considered a phrasal verb.

Why do students struggle with phrasal verbs?

Before teaching anything, it is worth considering why learners may find it challenging. Trainee teachers sometimes treat them mainly as grammar. In practice, the main difficulty is lexical ie, the students struggle with meaning.

First, the meaning is often non-transparent. Learners may know the verb and the particle separately but not the combined meaning.

Second, one verb can combine with many particles. Take off (the plane took off), take up (I took up skiing), take over (she took over as manager) , and take back (I took back what I'd said about her) all differ in meaning.

Third, one phrasal verb can have several meanings. Pick up can mean collect someone, improve, learn informally, or answer the phone.

Finally, word order creates confusion with separable verbs, as we'll discuss below.

Thinking about these problems first helps you design clearer lessons. A lesson about phrasal verbs is not necessarily teaching a "rule". You are helping learners build a network of lexical items.

Transitive and intransitive phrasal verbs

Like other verbs, phrasal verbs can be transitive or intransitive.

An intransitive phrasal verb does not take an object:

• The plane took OFF.

• He grew UP in Dublin.

• The meeting broke UP.

A transitive phrasal verb takes an object:

• She turned OFF the lights.

• They put OFF the meeting.

• I looked UP the word.

If a phrasal verb is transitive, you then need to consider whether it is separable.

Separable and inseparable phrasal verbs

Some transitive phrasal verbs are separable. The object can go between the verb and the particle.

• Turn off the lights.

• Turn the lights off.

If the object is a pronoun, it must go between the verb and the particle:

• Turn them off.

• Not Turn off them.

Other phrasal verbs are inseparable:

• Look after the children.

• Not Look the children after.

• Run into an old friend.

• Not Run an old friend into.

This may feel instinctive to a native speaker, but not to a student.

Word stress and pronunciation

In many phrasal verbs, the main stress falls on the particle:

• turn OFF

• look UP

• give UP

As with any new vocabulary, it is worth modelling clearly and drilling naturally.

At higher levels, you can show how stress shifts when a related noun is formed:

• a TAKE-off

• a BREAK-up

How course books organise phrasal verbs

Course books tend to group phrasal verbs in two main ways.

One approach is thematic. For example, a unit on relationships might include get on with, fall out with, fall for, and go out with. The advantage is that the verbs are tied to a clear context and topic. This can support meaning and recall.

Another approach is to group them by base verb, such as take after, take away, take on, and take up. This can highlight patterns and differences in meaning. It may also help learners see how one verb combines with multiple particles. The risk is cognitive overload if too many meanings are introduced at once.

Both approaches are valid. Your choice depends on level, lesson aims, and the wider syllabus.

Classroom approaches

A strong context is essential. Rather than presenting a long list, embed phrasal verbs in a reading or listening text. Let learners encounter them in use before analysing them. When clarifying meaning, use concept checking questions and short, clear examples that relate to the context.

Boardwork should make form explicit. Mark the verb and particle clearly, show whether the verb is transitive or intransitive, and demonstrate word order with pronouns where relevant.

Recycling, homework and practice really matter. Phrasal verbs need repeated exposure. Encourage learners to record them with example sentences and context, not as isolated pairs of words.

Conclusion

A phrasal verb is a verb plus a particle, which is either an adverb or a preposition, forming a single lexical unit. It can be transitive or intransitive, and transitive phrasal verbs may be separable or inseparable. Stress typically falls on the particle in the verb form.

For teachers, the key is to treat phrasal verbs primarily as lexis (vocabulary), supported by clear attention to form. With thoughtful staging, strong context, and regular recycling, they become far less mysterious for both teacher and learner.
