The noun 'breakfast' is recorded as being used in English since the middle of the 15th century.
It is assumed by etymologists that the word is a contraction of the phrase 'breaking (one's) fast', meaning that overnight one fasts - doesn't eat - during sleep and, shortly after awakening, one breaks fast, or has breakfast.
From the 1670s the word is recorded in use as a verb, for example:
This morning I had a great breakfast: my hosts decided we would all breakfast on the full traditional meal of bacon, eggs, toast, and so on.
