To breed or reproduce; to bear offspring (archaic or dialect).
From Old English abredan or from Middle English abreden. The prefix a- combined with breed creates an intensified or completed action. This term is now archaic, replaced by standard 'breed' in modern English.
Words like abreed show how Old English added prefixes to intensify verbs—'abreed' meant to actively produce offspring—but English gradually simplified, dropping these prefixes until they felt archaic.
