Could you please tell me if the following sentences are gramatically correct:
1 - He always goes to sleep very late.
2 - He always goes sleeping very late.
3 - She loves to go sleeping late.
4 - She loves to go to sleep late.
#1 is fine. #2 and #3 are incorrect.
#4 is grammatically acceptable, but we would normally say "She loves to go to bed late". We don't normally have control over when we actually go to sleep.
