Phrasal verbs can be divided into groups:
The object must come after the particle.
They are looking after their grandchildren.
With some separable verbs, the object must come between the verb and the particle:
The quality of their work sets them apart from their rivals.
In our phrasal verb dictionary, we classify these as Separable [obligatory]
With some separable verbs, the object can before or after the particle, though when a pronoun is used it comes before the particle:
Turn the TV off.
Turn off the TV.
Turn it off.
In our phrasal verb dictionary, we classify these as Separable [optional]
