Phrasal verbs are mainly used in spoken English and informal texts. (The more formal a conversation or text, the less phrasal verbs are found.)
Phrasal verbs consist of a verb plus a particle (preposition, adverb). The particle can change the meaning of the verb completely, e.g.:
look up – consult a reference book (look a word up in a dictionary)
look for – seek (look for her ring)
look forward – anticipate with pleasure (look forward to meeting someone)
There are no rules that might explain how phrasal verbs are formed correctly – all you can do is look them up in a good dictionary and study their meanings. In our lists, you will find some frequently used phrasal verbs and their meanings.
Position of the Particle
The particle is placed either after the verb or after the object.
Example: Write down the word. / Write the word down.
If the object is a pronoun, however, the particle has to be placed after the pronoun (object).
Example: Write it down
