One who blaves or speaks in a boastful manner; an archaic or dialectal term for a braggart.
From the verb blave (to boast, speak loudly) plus the agent noun suffix -er. The root blave is of obscure origin, possibly Scandinavian or Low German.
Blaver shows how English creates character descriptions by adding -er to verbs—'a blaver' is literally 'someone who blaves,' and these simple word formations have been building English vocabulary for centuries.
