Phrasal Verbs: A Practical Teaching Guide
A phrasal verb is a verb plus a small word such as off, up or after, working as one unit: turn off, get up, look after. The meaning usually cannot be built from the parts, and the word order changes from one verb to the next.
What counts as a phrasal verb
Two elements make the form: a verb and a particle. The particle is usually an adverb or a preposition, and together with the verb it carries one meaning. Give up does not mean give, and find out does not mean find. Teach the pair as a single item from the first lesson, with its own entry on the board.
Three structures, kept apart
- Separable. With a full noun object, the particle may follow the verb or the object: turn the light off and turn off the light are both correct. With a pronoun, the object must go in the middle: turn it off.
- Inseparable. The object stays after the particle: look after the children, run into an old friend. Putting the object in the middle breaks the phrase.
- Intransitive. There is no object at all: get up, set off, come back, show up. These are the safest to introduce first.
The passive voice guide takes the separable group one step further: a separable verb keeps its particle in the passive, as in The light was turned off.
One verb, several particles
Teaching take with four particles shows why the particle carries the meaning. Take off is to remove something or to leave the ground. Take up is to start a hobby. Take after is to resemble a relative. Take over is to gain control. Show the four in a single column beside the one verb, then move straight into sentences, because four definitions without four examples turn into a vocabulary list.
Literal and idiomatic meanings
Many phrasal verbs have both readings, and the literal one is a useful first step. Pick up a box describes a hand movement; pick up a language describes learning it without formal study. Put out the lights sits close to the literal sense, while put someone out means to inconvenience them. Ask students to guess the literal picture first, then supply the second meaning.
Why students avoid them
Three reasons come up in class again and again. Students fear the word order, so they reach for a single Latin verb such as extinguish or tolerate instead. They believe phrasal verbs are informal, though find out and look after are ordinary in careful writing. And they have met the verbs only in a long list, which gives meanings but no practice.
A teaching order that works
- Start with intransitive verbs, where nothing can go wrong: get up, sit down, go out, come back.
- Add about twenty high-frequency inseparable verbs: look after, look for, wait for, listen to, depend on. Drill the position of the object until it is automatic.
- Introduce separable verbs last, with the pronoun rule in the same lesson: turn it off, pick it up, write them down.
- Only then widen the list, keeping the structure work going alongside the new meanings.
Three classroom drills
- Sort and build. Give out verb cards and particle cards. Teams build phrases and place each one under the heading separable, inseparable or intransitive.
- Move the object. Read a sentence with a noun object and ask for two versions: She picked the children up. / She picked up the children. Then repeat it with them, where only one version survives.
- Three verbs, one story. Students tell a four-sentence story about their morning using get up, find out and give up. The story makes the meaning do work instead of the definition.
Six errors to correct on the board
- *look the word after for look after the word, an inseparable verb split in two.
- *turn off it for turn it off, a pronoun in the wrong position.
- *put on it in the same pattern; the pronoun belongs between verb and particle.
- Treating the particle as a stray preposition and moving it to the end of the clause.
- Dropping the particle in a question: *What time did you get?
- Swapping particles between similar verbs, so that look for and look after lose their difference.
Phrasal verbs and prepositional verbs
The two descriptions overlap. In a phrasal verb the particle works with the verb as one unit, and a separable verb lets the object move between them. In a prepositional verb the word after the verb keeps its prepositional job, and the object has to follow it: look at the map, listen to the recording. A practical test: if the object can go before the small word, treat the verb as phrasal; if it cannot, treat it as prepositional. Some items are analysed both ways by different references, so pick the description your textbook uses and stay with it. One detail worth teaching early is the verb after a prepositional verb, which takes the -ing form, as the gerunds and infinitives guide sets out: look forward to seeing you, never look forward to see you.
What to expect at A2 and B1
At A2, aim for intransitive and inseparable high-frequency verbs used in the present and past simple: get up, go out, wake up, look after, listen to. Add separable verbs with nouns only, such as put your coat on. At B1, bring in the pronoun rule, the separable and inseparable split, and the gerund after prepositional verbs. Asking an A2 class for turn it off before they can manage turn the light off reverses the order the structure is learned in.
Frequently asked questions
Are phrasal verbs informal?
No. Many are neutral and appear in careful writing: find out, look after, get up, set up. A few sit closer to speech, but the group as a whole is ordinary English rather than slang.
How many phrasal verbs should a B1 student learn?
A workable target is twenty to thirty high-frequency items used with confidence, rather than a list of two hundred met once. Choose the verbs the class already meets in its reading.
Why can I say turn the light off but not turn off it?
A pronoun object has to sit between the verb and the particle: turn it off. A full noun object is free to move, so turn the light off and turn off the light are both correct.
Is look after a phrasal verb or a prepositional verb?
References put it in different groups, which is a sign that the boundary is not sharp. What matters in class is that the object cannot go in the middle: look after the children, never look the children after.
Should students learn phrasal verbs from a list?
Not as a first step. Lists help once the class can use the three structures; before that, a list teaches meanings without the word order that makes them usable.
