Thanx so much. Can you point where we can learn all this. These days it's hard to grab all that even when you read books a bit everyday
Ironically though, your reply has another similar one. You read books every day; reading books is an everyday activity for you.
Write a sentence and ask it it is correct, if it is idiomatic, and to explain rules behind it.
- set up [1] (notice that it's a verb)
- setup [2] (notice that it's a noun)
- Phrasal verbs [3]
Unfortunately, I'm afraid it's mostly stuff one needs to know by heart, but I think it's often that the noun is the one that is all in one word and the verb is the phrasal one (composed of "base" and the particle, in several words). Note: I'm not a native English speaker.
