factotum: [16] A factotum is literally someone who ‘does everything’. It was coined from fac, the imperative form of the Latin verb facere ‘do’, and tōtum ‘all’ (source of English total). Originally it was used virtually as a name, in phrases such as ‘Master Factotum’, and it does not seem to have been until the late 18th century that it settled into its current role as an ordinary noun. => fact, total
