An archaic verb meaning to help thoroughly or to be of great assistance to someone.
From 'be-' (thoroughly, intensively) + 'help' (to assist). Like other 'be-' verbs, this intensified the basic meaning into something more complete or comprehensive.
Middle English writers used 'behelp' in situations requiring earnest, total assistance—if you 'behelped' someone, you didn't just lend a hand, you gave substantial support, showing how prefixes once added emotional weight to verbs.
