baster

The word 'baster' is a straightforward agent noun derived from the culinary verb 'baste'. The verb 'baste' entered English in the late 14th century, likely from the Old French 'basser', meaning to soak or moisten, though its deeper origins are obscure and may be onomatopoeic, imitating the sizzling sound of liquid hitting hot food. The suffix '-er', a productive agent-forming suffix from Old English, is appended to create a noun denoting either the person performing the action or, more commonly in modern usage, the tool designed for that specific task. Thus, the literal "moistener" evolved into the specific modern implement used to keep roasting meat juicy and flavorful.
