How to stress phrasal verbs?

First of all, we must understand what is the difference between an adverb and a preposition, although they are both particles.

An adverb is a particle without a noun behind it. For example, "his career takes off".

A preposition is a particle followed with a noun. For instance, "he has looked for a job."

Usually we stress the particle, except for inseparable phrasal verbs.

1) Inseparable phrasal verbs:

• Unstress the preposition (E.g. I’m looking for a job.)

• Stress the adverb (E.g. They made off when the police arrived.)

2) Separable phrasal verbs:

• When the object is a pronoun, stress the particle (E.g. Turn it on.)

• When the object is a noun coming between the verb and particle, stress the noun (E.g. Turn the light on.)

• When the object is a noun coming after the verb and particle, stress the particle. (E.g. Turn on the light.)

3) Three-part phrasal verbs:

• stress the first particle

E.g. I'll make up for it.

E.g. I’ll catch up with you later.

E.g. I can’t put up with him anymore.

E.g. They won’t get away with it.
