A thing that really confuses me is the difference between those 4 verbs.
Ok, some cases are really well known and defined (i.e. "I speak English", "How do you say that word?") but others are confusing.
Let me do some examples:
(Interrupting someone) May I X something?
(When you don't want to be interrupted) Let me X !
I X the truth
What I was X is...
I want to X you a thing
Can you choose the correct verb/s for each sentence and explain me some rule?
Also some example would be very appreciate!
