chesty (adj.)

Middle English chest, from Old English cest "box, coffer, casket," usually large and with a hinged lid, from Proto-Germanic *kista (source also of Old Norse and Old High German kista, Old Frisian, Middle Dutch, German kiste, Dutch kist). This is an early borrowing from Latin cista "chest, box," from Greek kistē "a box, basket," from PIE *kista "woven container" (Beekes compares Middle Irish cess "basket, causeway of wickerwork, bee-hive," Old Welsh cest).

The meaning of the English word was extended to "thorax, trunk of the body from the neck to the diaphragm" c. 1400, replacing breast (n.) in that sense, on the metaphor of the ribs as a "box" for the heart.

The meaning "place where public money is kept (common chest, mid-15c.) was extended to "public funds" (1580s). Chest of drawers is from 1670s.

late Old English prud, prute "excellent, splendid; arrogant, haughty, having or cherishing a high opinion of one's own merits; guilty of the sin of Pride," from Old French prud, oblique case of adjective prouz "brave, valiant" (11c., Modern French preux; compare prud'homme "brave man"), from Late Latin prode "advantageous, profitable" (source also of Italian prode "valiant"), a back-formation from Latin prodesse "be useful."

This is a compound of pro- "before, for, instead of" (from PIE root *per- (1) "forward," hence "in front of, before, first, chief") + esse "to be" (from PIE root *es- "to be"). Also see pride (n.), prowess. "The -d- in prodesse is probably due to the influence of forms like red-eo-, 'I go back,' red-imo- 'I buy back,' etc." [OED]. The Old English form with -te probably is from or influenced by pride (Old English pryto).

Meaning "elated by some act, fact, or thing" is from mid-13c. The sense of "of fearless or untamable spirit" is by c. 1400; that of "ostentatious, grand, giving reason for pride" is by mid-14c. To do (someone) proud is attested by 1819. The surname Proudfoot is attested from c. 1200 (Prudfot). A Middle English term for "drunk and belligerent" was pitcher-proud (early 15c.).

The sense of "having a high opinion of oneself," not found in Old French, might reflect the Anglo-Saxons' opinion of the Norman knights who called themselves "proud." Old Norse pruðr, either from the same French source or borrowed from Old English, had only the sense "brave, gallant, magnificent, stately" (compare Icelandic pruður, Middle Swedish prudh, Middle Danish prud).

Likewise a group of "pride" words in the Romance languages — such as French orgueil, Italian orgoglio, Spanish orgullo — are borrowings from Germanic, where they had positive senses (Old High German urgol "distinguished").

Most Indo-European languages use the same word for "proud" in its good and bad senses, but in many the bad sense seems to be the earlier one. The usual way to form the word is by some compound of terms for "over" or "high" and words for "heart," "mood," "thought," or "appearance;" such as Greek hyperephanos, literally "over-appearing;" Gothic hauhþuhts, literally "high-conscience." Old English had ofermodig "over-moody" ("mood" in Anglo-Saxon was a much more potent word than presently) and heahheort "high-heart."

Words for "proud" in other Indo-European languages sometimes reflect a physical sense of being swollen or puffed up; such as Welsh balch, probably from a root meaning "to swell," and Modern Greek kamari, from ancient Greek kamarou "furnish with a vault or arched cover," with a sense evolution via "make an arch," to "puff out the chest," to "be puffed up" (compare English slang chesty).

adjective suffix, "full of or characterized by," from Old English -ig, from Proto-Germanic *-iga- (source also of Dutch, Danish, German -ig, Gothic -egs), from PIE -(i)ko-, adjectival suffix, cognate with elements in Greek -ikos, Latin -icus (see -ic).

Originally added to nouns in Old English; it was used from 13c. with verbs, and by 15c. with other adjectives (for example crispy).

Variant forms in -y for short, common adjectives (vasty, hugy) helped poets keep step with classical feet when the grammatically empty but metrically useful -e dropped off such words in late Middle English. To replace it, by Elizabethan times, verse-writers had adapted to -y forms, and often it was done artfully, as in Sackville's "The wide waste places, and the hugy plain." Simple huge plain would have been a metrical balk.

After Coleridge's criticism of the -y forms as archaic artifice, poets gave up stilly (Moore probably was last to get away with it, with "Oft in the Stilly Night"), paly (which Keats and Coleridge himself had used) and the rest. Jespersen ("Modern English Grammar," 1954) also lists bleaky (Dryden), bluey, greeny, and other color words, lanky, plumpy, stouty, and the slang rummy. Vasty survived, he said, only in imitation of Shakespeare; cooly and moisty (Chaucer, hence Spenser) he regarded as fully obsolete. But in a few cases he notes (haughty, dusky) they seem to have supplanted the shorter forms.
