#### Usage notes

With almost any of the transitive senses except sense 1, the object may appear before or after the particle if the object is a noun or noun phrase:
    He blew the room up without blowing up the building.
If the object is a pronoun, then the pronoun must come before the particle:
    Try not to blow it up.
    (Putting up between the verb and the pronoun, as in "blow up it", converts the particle into a preposition, and thus changes the meaning.)

#### Derived terms

* blow me up
* blow someone's skirt up
