Something that has been particularly confusing for me is figuring out which phrasal verbs are considered "separable" and which are considered "inseparable." I found this site (linked at the title of this post), which lists many common separable and inseparable phrasal verbs, but I think I still get confused about some of them. Is separating a separable phrasal verb considered bad for your writing style?
For instance, is it better to say
I need to pick up my parents from the airport.
I need to pick my parents up from the airport.?
