To vaunt one's self; to brag; to say or tell things which are intended to give others a high opinion of one's self or of things belonging to one's self; as, to boast of one's exploits courage, descent, wealth.
Nowadays we might say that boasting is a big-headed thing to do, but to the Anglo-Saxons it meant something quite different. A boast was a kind of promise a warrior made in front of other people. When a warrior had boasted that he would carry out a brave action and everyone had heard it, then he had to do it. If he succeeded (or even if he died trying) his would be talked about and praised. If he did not, he would not be respected any more. Back
