I'm confused as to where I should place nouns/phrases when using two-word verbs. I've seen both of the following, so I'm unsure.
Why is no one picking up the phone?
Why is no one picking the phone up?
Why isn't anyone picking up their stuff?
Why isn't anyone picking their stuff up?
I was taught that I should use verb together + noun/prhase if the phrase or the noun that accompanies a two-word verb is long, and that I should use first part of the verb + a short noun/phrase + the second part of the verb if the noun/phrase is short.
But I have no idea just how much is considered long/short.
