Word Origin and History for stems

stem

n.

Old English stemn, stefn "stem of a plant," also "either end-post of a ship," from Proto-Germanic *stamniz (cf. Old Saxon stamm, Old Norse stafn "stem of a ship;" Danish stamme, Swedish stam "trunk of a tree;" Old High German stam, German Stamm), from PIE root *sta- "to stand" (see stet).

Meaning "support of a wineglass" is from 1835. Stem-winding watches (1875) were advanced and desirable when introduced, hence slang stem-winder "excellent thing" (1892). The nautical sense is preserved in the phrase stem to stern "along the full length" (of a ship), attested from 1620s. The verbal phrase stems from, first recorded 1932, American English, translates German stammen aus, probably from a figurative sense represented by English stem (n.) in the sense of "stock of a family, line of descent" (c.1540; cf. family tree, and German stammvater "tribal ancestor," literally "stem-father"). Stem cell attested by 1885.

stem

v.

"to hold back," c.1300, from Old Norse stemma "to stop," from Proto-Germanic *stamjan (cf. Swedish stämma, Old Saxon stemmian, Middle Dutch stemon, German stemmen "stop, resist, oppose"), from PIE root *stem- "to strike against something" (cf. Lithuanian stumiu "thrust, push"). Phrase to stem the tide is literally "to hold back the tide," but often is confused with stem (v.) in sense of "to make headway against, head in a certain course" (late 14c.), which is from stem (n.)).

stems in Science

stem

[stĕm]
  1. The main, often long or slender part of a plant that usually grows upward above the ground and supports other parts, such as branches and leaves. Plants have evolved a number of tissue arrangements in the stem. Seedless vascular plants (such as mosses and ferns) have primary vascular tissue in an inner core, a cylindrical ring, or individual strands scattered amid the ground tissue. In eudicots, magnoliids, and conifers, the stem develops a continuous cylindrical layer or a ring of separate bundles of vascular tissue (including secondary vascular tissue) embedded in the ground tissue. In monocots and some herbaceous eudicots, individual strands of primary vascular tissue are scattered in the ground tissue.
  2. A slender stalk supporting or connecting another plant part, such as a leaf or flower.
