(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.
(v. i.) To move forward against an obstacle, as a vessel against a current.
Example Sentences:
