VERB + ADVERB and/or PREPOSITION

The adverb or preposition is called a particle.

Before we go any further let’s make sure we are all clear on what a verb, a preposition and an adverb are.

A verb is a word that describes an action (i.e. to swim, to read), or a state of being (i.e. to live, to understand). Every sentence has to have a verb.
A preposition is a small word that describes the relationship between two words. For example, the cat is ON the chair or IN the drawer or UNDER the table or INSIDE the bag. Prepositions usually deal with time (i.e. SINCE, BY a certain time), location/place, (IN, BELOW, OPPOSITE) or direction/movement (i.e. ACROSS, DOWN).
An adverb is a word that describes a verb, an adjective or other adverbs.

Now that you know what verbs, adverbs, prepositions and particles are, you’re ready to start putting them together into phrasal verbs.
