More about tome
The noun tome comes from Middle French tome, from Latin tomus “a cut, slice, or bit; a piece or length of papyrus; a book (in general).” Tomus is a borrowing of Greek tómos “a slice” (e.g., of ham, cheese), (in geometry) “the frustum” (e.g., of a cylinder), “a beam” (of wood). By the 3rd century b.c. and in the Septuagint (the Greek version of the Hebrew Scriptures, dating between the 3rd and 1st centuries b.c.), tómos had also come to mean “(papyrus) roll,” and by the 1st century a.d. “tome, volume” (in the modern sense). Tómos is a derivative of the verb témnein “to cut,” from the Proto-Indo-European root tem-, tom– (with its extensions tend-, tond-) “to cut.” From the variant tem-, Latin derives templum “shrine, temple” (because the property has been cut out from, set apart from profane use). The variant tond- forms Latin tondēre “to cut or clip (hair), shear (a sheep)” and the agent noun tonsor (stem tonsōr-) “barber,” with its derivative adjective tonsōrius, from which English derives the not very serious adjective tonsorial “of or relating to a barber or barbering.” Tome entered English in the first half of the 16th century.
