Separable and Inseparable Phrasal Verbs
Some phrasal verbs separate the verb from the preposition(s) (or particles) while others do not. Phrasal verbs are either separable or inseparable.
Separable Phrasal Verbs
Separable phrasal verbs can either remain together when using an object that is a noun or noun phrase, or separate:
Example:
They picked up a new processor after the upgrade.
They put beta testing off until after taking the program to the marketplace.
It is important to remember that separable phrasal verbs MUST be separated when using a pronoun as an object of the phrasal verb.
Example:
The beta tester set the new gameboy down.
Steven set the QWERTY keyboard down on his desk.
Inseparable Phrasal Verbs
Inseparable phrasal verbs never separate and must remain together whether a noun, noun phrase or pronoun is used.
Example:
Shelly looked forward to opening the readme file.
I looked forward to adding more RAM to my computer.
Usage Tip
When you are not sure whether a phrasal verb is separable or inseparable, ALWAYS use a noun or noun phrase and DO NOT separate. As separable phrasal verbs must separate when using a pronoun, using the noun or noun phrase will help you avoid this problem and will always be correct.
