Welcome back! I am Teacher Sopheak. My intermediate students often ask me how to sound more like a native speaker. I always tell them the same thing: you must master Phrasal Verbs.

A phrasal verb combines a normal verb with a small word (like up, on, or for) to create a totally new meaning. Today, we will learn why some of these can be split apart, while others must stay glued together.

warning Watch Out: Pronoun Placement!

If the object is a pronoun (it, them, him, her), it MUST go in the middle of a separable verb.

In English, if the object of a separable phrasal verb is a pronoun (like it, them, him, her), you must place it in the middle of the verb. You cannot place it at the end.

Lesson Summary & Review

Let's review the key concepts covered in the interactive module above to ensure you are ready to use phrasal verbs naturally.

Separable vs. Inseparable Phrasal Verbs

Phrasal verbs are combinations of verbs and prepositions (or adverbs) that create a new meaning. They fall into two main categories:

• Separable: The object can go between the verb and the particle, or after the particle. (e.g., "Turn on the light" OR "Turn the light on"). Examples: Turn on, Pick up.
• Inseparable: The verb and particle must stay together. The object always comes after. (e.g., "I am looking for my keys"). Examples: Look for, Run into.

The Pronoun Rule

This is a critical rule for sounding fluent: If the object of a separable phrasal verb is a pronoun (it, them, him, her, me, us, you), it MUST go between the verb and the particle.

Correct: "Pick it up."

Incorrect: "Pick up it."
