Origin

This word comes from Middle English tool, from Old English tōl ("tool, implement"), literally "that with which one prepares something." It was perhaps borrowed from Old Norse tól, but ultimately traces back to Proto-Germanic *tōlą and the Proto-Indo-European root *dewh₂- ("to tie to, secure"). It is related to words like taw ("to prepare").
