@milimi,
Quote: If you tell somebody to come TO EAT (for eating) you must SAY
"come and eat" , "come to eat" Or both?
COME AND EAT would be the usual but this is used as a way to say the meal is ready. Also, LET'S EAT. or DINNER/LUNCH/BREAKFAST IS ON.
Quote:Same question for "go and eat" and "go to eat".
Thank you.
GO AND EAT would see use when one person is telling another to go eat but the person telling isn't joining in at that time.
Example: Go and eat. I'll watch/feed/take care of the baby.
