I have some doubts about phrasal verbs and object pronouns. With a verb such as LOOK AFTER, which is inseparable (isn't it?), can you say" I will look them after", or the only possibility is" I will look after them", even if the object is a pronoun. I had the idea that most transitive phrasal verbs allow to place the object in between or after the particle if it is a noun, but when it is a pronoun it must be placed bewtween verb and particle. Therefore, in the case or LOOK AFTER, for example, is that possible? As usual, thanks in advance for your help.
