A person or device that fumbles or causes fumbling; something designed to handle or grope around.
From 'fumble' plus '-ator' (a Latin suffix for 'one who does' or 'that which does'), creating an agency noun.
The suffix '-ator' is Latin and supremely useful—it lets us name anything that performs an action, from 'calculator' to 'fumbulator,' giving English a vocabulary for describing tools and people!
