Origin & History of “tool”
A tool is etymologically an implement used to ‘make’ something. It came from a prehistoric Germanic *tōwlam. this was derived from a base *tōw-, *taw-, which produced a variety of other words with the general sense ‘make, prepare, do’ (most of them have now died out, but survivors include Dutch touwen and English taw ‘make leather’).
