JET (1),
to throw out, fling about, spout. (F.,—L.) In
Tudor-English it commonly means to fling about the body, to strut about, to
stalk about proudly. 'How he jets under his advanced plumes;'
Tw. Nt. ii. 5. 36. 'Then must ye stately goe, ietting vp and
downe;' Ralph Roister Doister, A. iii. sc. 3. l. 121 (in Spec. of Eng. ed.
Skeat). M.E. getten, ietten; see Prompt. Parv. pp.
192, 258, and Way's notes. 'I iette, I make a countenance
with my legges, ie me iamboye; I iette with facyon and countenance
to sette forthe myselfe, ie braggue;' Palsgrave.—O.F. jetter,
jecter, also getter, 'to cast, hurl, throw, fling, dart or send out
violently, put or push forth;' Cot.—Lat. iactare, to fling,
frequent. of iacere, to throw. β. Lat. iacere is certainly
closely related to Gk.
ἰάπτειν, to throw; see
Iambic. Der.
jet, sb.,
M.E. get, in early use in the sense of 'fashion;' cf. 'Get, or maner of custome,
Modus, consuetudo,' Prompt. Parv.; 'al of the newe get' = all in the new
fashion, Chaucer, c. T. 684; this answers to O.F. iect
or gec (mod. F. jet), which Cot. explains by 'a cast or throw, as
at dice.' [The mod. sense of jet is a spout of water, as in
Pope, Duncaid, ii. 177.] Hence also jetteau, Spectator, no.
412, written for F. jet ďeau = a spout of water, a fountain (where F.
eau = Lat. aqua, water). Also jet-sam, q.v.,
jett-y,
q.v. ➩ From Lat.
iacere (pp. iactus) are numerous derivatives;
as, ab-ject, ad-ject-ive, con-ject-ure, de-ject, e-ject, in-ject, inter-ject-ion,
ob-ject, pro-ject, re-ject, sub-ject; also ad-jac-ent, e-jac-ulate; also
amice,
gist, joist, jesses.
JET (2),
a black mineral, used for ornaments. (F.,—L.,—Gk.)
'His bill was blak, and as the jet is shon;' Chaucer, C. T. 14867.—O.F.
jet, jaet, gayet, gagate, 'jet;' Cot.—Lat. gagatem, acc. of găgātes,
jet (whence the forms gagate, gayet, jaet, jet in successive order of
development); see Trevisa, ii. 17, where the Lat. has gagates, Trevisa has
gagates, and the later E. version has iette. Described in Pliny,
xxxvi. 19.—Gk. γαγάτης, jet; so called from
Γάγας, or
Γάγγαι, a town and
river in Lycia, in the S. of Asia Minor. Der. jet-black; jett-y,
Chapman, tr. of Homer, Il. ii. 629; jett-i-ness.
