吃早饭英文怎么说能用eat吗

Yes, "eat" can be used to say "have breakfast" in Engpsh. The verb "eat" is a general term that can be used to describe the action of consuming food. It can also be used specifically to refer to a meal, such as breakfast, lunch, or dinner. The word "breakfast" itself comes from the Old Engpsh word "brecfast" which means "to break the fast" since it is the first meal of the day after a night of not eating.
