clam [clam 词源字典]: clam: [OE] Old English clam meant ‘something for tying up or fastening, fetter’; it can be traced back to a prehistoric Germanic base *klam-, which also produced clamp [14] and is related to climb. There is a gap in the word’s history in early Middle English times, but it reappears at the end of the 14th century in the sense ‘clamp’, and in the 16th century it was applied, originally in Scotland, to the mollusc which now bears the name, apparently on the grounds that its two shells close like the jaws of a clamp or vice.

crocodile: crocodile: [13] The crocodile gets its name from its habit of basking in the sun on sandbanks or on the shores of rivers. The word means literally ‘pebble-worm’, and it was coined in Greek from the nouns krókē ‘pebbles’ and drilos ‘worm’. The resulting Greek compound *krokódrīlos has never actually been found, for it lost its second r, giving krokódīlos, and this r reappeared and disappeared capriciously during the word’s journey through Latin and Old French to English. Middle English had it – the 13th century form was cokodrille – but in the 16th century the modern r-less form took over, based on Latin crocodīlus.
exploit: exploit: [14] Latin explicāre (source of English explicate and explicit) meant ‘unfold’. A Vulgar Latin descendant of its past participle was *explictum ‘something unfolded’, which passed into Old French as exploit or esplait. In the process, the original sense of ‘unfolding’ had developed through ‘bringing out, development’ and ‘advantage, success’ to ‘achievement’.

In the case of the English noun, it is the latter meaning which has survived, and in fact originally the verb too denoted ‘achieve, accomplish’. This seems to have died out in the 18th century, however, and when the verb reappears in the 19th century it is closer to the earlier ‘develop’ in meaning, particularly as applied to ‘getting the most out of’ natural resources. The modern derogatory sense ‘use for one’s own selfish ends’ emerged from this.

thimble: thimble: [OE] A thimble is etymologically a ‘thumb implement’. The word goes back to Old English thymel, a derivative of thūma ‘thumb’. In Old English (where it is recorded only once) it was used for a ‘finger-stall’. By the time it reappears in the 15th century we find it being applied to a ‘leather finger-protector used for pushing in a needle’, and it was extended to metal thimbles, introduced in the 17th century.

coerce (v.): mid-15c., cohercen, from Middle French cohercer, from Latin coercere "to control, restrain, shut up together," from com- "together" (see co-) + arcere "to enclose, confine, contain, ward off," from PIE *ark- "to hold, contain, guard" (see arcane). Related: Coerced; coercing. No record of the word between late 15c. and mid-17c.; its reappearance 1650s is perhaps a back-formation from coercion.
dot (n.): Old English dott "speck, head of a boil," perhaps related to Norwegian dot "lump, small knot," Dutch dot "knot, small bunch, wisp," Old High German tutta "nipple;" ultimate origin unclear.

Known from a single source c. 1000; the word reappeared with modern meaning "mark" c. 1530; not common until 18c. Morse telegraph sense is from 1838. On the dot "punctual" is 1909, in reference to a clock dial face. Dot-matrix first attested 1975.
emersion (n.): "reappearance, act of emerging," 1630s, noun of action from past participle stem of Latin emergere "to rise out or up" (see emerge). Originally of eclipses and occultations.
expert (n.): early 15c., "person wise through experience," from expert (adj.). The word reappeared 1825 in the legal sense, "person who, by virtue of special acquired knowledge or experience on a subject, presumably not within the knowledge of men generally, may testify in a court of justice to matters of opinion thereon, as distinguished from ordinary witnesses, who can in general testify only to facts" [Century Dictionary].
festive (adj.): 1650s, "pertaining to a feast," from Latin festivus "festive, joyous, gay," from festum "festival, holiday," noun use of neuter of adjective festus (see feast (n.)). The word is unattested in English from 1651 to 1735 (it reappears in a poem by William Somervile, with the sense "fond of feasting, jovial"), and the modern use may be a back-formation from festivity. Meaning "mirthful, joyous" in English is attested by 1774. Related: Festively; festiveness.
When the Day crown'd with rural, chaste Delight
Resigns obsequious to the festive Night;
The festive Night awakes th' harmonious Lay,
And in sweet Verse recounts the Triumphs of the Day.

[Somervile, "The Chace"]
Earlier adjectives in English based on the Latin word were festival "pertaining to a church feast" (late 14c.); festful "joyous" (early 15c.), festial "pertaining to a church feast" (early 15c.), festli "fond of festivity" (late 14c.).
latrine (n.): c. 1300, probably from Latin latrina, contraction of lavatrina "washbasin, washroom," from lavatus, past participle of lavare "to wash" (see lave) + -trina, suffix denoting "workplace." Its reappearance in 1640s is probably a re-borrowing from French; especially of a privy of a camp, barracks, college, hospital, etc. Latrine rumor "baseless gossip" (of the kind that spreads in conversations in latrines) is military slang, first recorded 1918.
re-appear (v.): also reappear, 1610s, from re- "back, again" + appear. Related: Reappeared; reappearing.
re-appearance (n.): also reappearance, 1660s; see reappear + -ance.
Renaissance (n.): "great period of revival of classical-based art and learning in Europe that began in the fourteenth century," 1840, from French renaissance des lettres, from Old French renaissance, literally "rebirth," usually in a spiritual sense, from renastre "grow anew" (of plants), "be reborn" (Modern French renaître), from Vulgar Latin *renascere, from Latin renasci "be born again, rise again, reappear, be renewed," from re- "again" (see re-) + nasci "be born" (Old Latin gnasci; see genus).

An earlier term for it was revival of learning (1785). In general usage, with a lower-case r-, "a revival" of anything that has long been in decay or disuse (especially of learning, literature, art), it is attested from 1872. Renaissance man is first recorded 1906.
Seth: masc. proper name, Biblical third son of Adam, literally "set, appointed," from Hebrew Sheth, from shith "to put, set." The Gnostic sect of Sethites (2c.) believed Christ was a reappearance of Seth, whom they venerated as the first spiritual man.
thicket (n.): "close-set growth of shrubs, bushes, trees, etc.," late Old English þiccet, from þicce (see thick) + denominative suffix -et. Absent in Middle English, reappearing early 16c., perhaps a dialectal survival or a re-formation.
Thule: region or island at northernmost part of the world, Old English, from Latin, from Greek Thyle "land six days' sail north of Britain" (Strabo, quoting a lost portion of a work by Polybius, itself based on a lost account of a voyage to the north by 4c. B.C.E. geographer Pytheas). The identity of the place and the source of the name have sparked much speculation; Polybius doubted the whole thing, and since Roman times the name has been used in a transferred sense of "extreme limits of travel" (Ultima Thule).
The barbarians showed us where the sun set. For it happened in those places that the night was extremely short, lasting only two or three hours; and the sun sunk under the horizon, after a short interval reappeared at his rising." [Pytheas]
The name was given to a trading post in Greenland in 1910, site of a U.S. air base in World War II.
bo-peep: "A quick look", Early 16th century (originally denoting a game of hiding and reappearing): from bo, an exclamation intended to startle someone (compare with boo¹) + the verb peep¹. The current sense dates from the 1940s.
