n.2“limitation of ownership,” a legal term, early 14c. in Anglo-French; late 13c. in Anglo-Latin, in most cases a shortened form of entail. v.“follow secretly,” U.S. colloquial, 1907, is from earlier sense of “follow or drive cattle,” from tail (n.1). Related: Tailed; tailing. Tail off “diminish” is attested from 1854. n.1“hindmost part of an animal,” Old English tægl, tægel, from Proto-Germanic *tagla- (cf. Old High German zagal, German Zagel “tail,” dialectal German Zagel “penis,” Old Norse tagl “horse’s tail”), from PIE *doklos, from root *dek- “something long and thin” (referring to such things as fringe, lock of hair, horsetail; cf. Old Irish dual “lock of hair,” Sanskrit dasah “fringe, wick”). The primary sense, at least in Germanic, seems to have been “hairy tail,” or just “tuft of hair,” but already in Old English the word was applied to the hairless “tails” of worms, bees, etc. Another Old English word for “tail” was steort (see stark). Meaning “reverse side of a coin” is from 1680s; that of “backside of a person, buttocks” is recorded from c.1300; slang sense of “pudenda” is from mid-14c.; that of “woman as sex object” is from 1933, earlier “prostitute” (1846). The tail-race (1776) is the part of a mill race below the wheel. To turn tail “take flight” (1580s) originally was a term in falconry. The image of the tail wagging the dog is attested from 1907. n.

  2. A long, stream of gas or dust forced from the head of a comet when it is close to the Sun. Tails can be up to 150 million km (93 million miles) long, and they always point away from the Sun because of the force of the solar wind.Plasma tails, or ion tails, appear bluish and straight and narrow, and are formed when solar wind forces ionized gas to stream off the coma. Dust tails are wide and curved, and are formed when solar heat forces trails of dust off the coma; solid particles reflecting the Sun’s light create their bright yellow color.
