An archaic form meaning to implore, beseech, or earnestly request someone for help or mercy.
From Old French emplorer, from em- (in) + plorer (to weep or cry). Related to 'implore,' it literally meant to bring into a state of weeping or pleading.
The difference between 'emplore' and 'implore' shows how English quietly dropped the 'em-' prefix from older verbs—'emplore' was the original form that sounded more dramatic, like your desperation was literally being placed INTO the request.
