as a suffix forming adjectives, it represents O.E.
-sum (see
some; cf. O.Fris.
-sum, Ger.
-sam, O.N.
-samr), related to
sama "same." As a suffix added to numerals meaning "a group of that number" (cf.
twosome) it represents O.E.
sum "some," used after the genitive plural (cf.
sixa sum "six-some"), the inflection disappearing in M.E. Use of
some with a number meaning "approximately" also was in O.E.
