tome: [16] Tome comes via French tome and Latin tomus from Greek tómos. This originally meant ‘slice, piece’ (it went back to the prehistoric Indo-European base *tom-, *tem- ‘cut’, which is also responsible for English temple, tonsorial [19], tonsure [14], and the surgical suffix -tomy ‘cutting’), but it was extended metaphorically to a ‘cut roll of paper’ and eventually to a ‘volume, book’.
