Inventress → It is formed from "invent" (from Latin "invenire", meaning to find or discover) and "-ess" (a suffix used to denote a female). The word "inventress" refers to a female inventor or one who discovers or creates something.
Think of someone who 'finds' or 'discovers' ('invenire') new ideas and is a 'female' ('-ess') — that's what an inventress is.
