Etymonline
Word Origin & History
sum
late 13c., "quantity or amount of money," from Anglo-Fr. and O.Fr. summe (13c.), from L. summa "total number, whole, essence, gist," noun use of fem. of summus "highest," from PIE *sup-mos-, from base *uper "over" (see super-). The sense development from "highest" to "total
EXPANDnumber" is probably via the Roman custom of adding up a stack of figures from the bottom and writing the sum at the top, rather than at the bottom as we do now (cf. the bottom line). Meaning "total number of anything" is recorded from late 14c. Meaning "essence of a writing or speech" also is attested from late 14c. The verb is attested from c.1300; meaning "briefly state the substance of" (now usually with up) is first recorded 1621. Sum-total is attested from c.1395, from M.L. summa totalis.
