Some phrasal verbs can be both: separable and non-separable.
Separable: A phrasal verb is said to be separable when a noun or pronoun object can come between the verb and the particle that make up the phrasal verb.
Non-separable: When a phrasal verb is described as non-separable, it means the particle cannot be separated from the verb; that is, a noun or pronoun object cannot come between the verb and the particle. The object can only come after the verb and the particle of the phrasal verb.
The following examples show words that make up a phrasal verb can be used both ways: separately and non-separately.
