Stem
Definition:
(v. i.) Alt. of Steem
(n.) Alt. of Steem
(n.) The principal body of a tree, shrub, or plant, of any kind; the main stock; the part which supports the branches or the head or top.
(n.) A little branch which connects a fruit, flower, or leaf with a main branch; a peduncle, pedicel, or petiole; as, the stem of an apple or a cherry.

(n.) The basal portion of the body of one of the Pennatulacea, or of a gorgonian.
(n.) The short perpendicular line added to the body of a note; the tail of a crotchet, quaver, semiquaver, etc.
(n.) The part of an inflected word which remains unchanged (except by euphonic variations) throughout a given inflection; theme; base.
(v. t.) To remove the stem or stems from; as, to stem cherries; to remove the stem and its appendages (ribs and veins) from; as, to stem tobacco leaves.
(v. t.) To ram, as clay, into a blasting hole.
(v. t.) To oppose or cut with, or as with, the stem of a vessel; to resist, or make progress against; to stop or check the flow of, as a current.
