clumpy (adj.)youdaoicibaDictYouDict
1820, from clump (n.) + -y (2). Also noted 1881 in an Isle of Wight glossary as a noun meaning "a stupid fellow." Related: Clumpily; clumpiness. Compare also clumperton "clown, clodhopper" (1530s).
clumsy (adj.)youdaoicibaDictYouDict
1590s, "acting as if benumbed," alteration of Middle English clumsid "numb with cold" (14c.), past participle of clumsen "to benumb, stiffen or paralyze with cold or fear," from a Scandinavian source akin to Old Norse klumsa "make speechless, palsy; prevent from speaking," intensive of kluma "to make motionless." For insertion of -s-, see flimsy.

Not in general use until 18c., with senses "manifesting awkwardness; so made as to be unwieldy." Related: Clumsily; clumsiness. Compare Swedish dialectal klummsen "benumbed with cold," Norwegian klumsad (past participle) "speechless, palsied by a spasm or by fear or witchery;" German verklammen "grow stiff or numb with cold." Also compare clumse (n.) "a stupid fellow."
lubber (n.)youdaoicibaDictYouDict
mid-14c., "big, clumsy, stupid fellow who lives in idleness," from lobre, earlier lobi "lazy lout," probably of Scandinavian origin (compare Swedish dialectal lubber "a plump, lazy fellow"). But OED suggests a possible connection with Old French lobeor "swindler, parasite," with sense altered by association with lob (n.) in the "bumpkin" sense. A sailors' word since 16c. (as in landlubber), but earliest attested use is of lazy monks (abbey-lubber). Compare also lubberwort, the name of the mythical herb that produces laziness (1540s); and Lubberland "imaginary land of plenty without work" (1590s). Sometimes also Lubbard (1580s).
lug (n.)youdaoicibaDictYouDict
1620s, "handle of a pitcher," from lugge (Scottish) "earflap of a cap, ear" (late 15c.; according to OED, the common word for "ear" in 19c. Scotland), probably from Scandinavian (compare Swedish lugg "forelock," Norwegian lugg "tuft of hair"). The connecting notion is "something that can be gripped and pulled." Applied 19c. to mechanical objects that can be grabbed or gripped. Meaning "stupid fellow" is from 1924; that of "lout, sponger" is 1931, American English. Compare lug-nut (1869), nut closed at one end as a cap.
trope (n.)youdaoicibaDictYouDict
1530s, from Latin tropus "a figure of speech," from Greek tropos "a turn, direction, course, way; manner, fashion," in rhetoric, "turn or figure of speech," related to trope "a turning" and trepein "to turn," from PIE root trep- (2) "to turn" (cognates: Sanskrit trapate "is ashamed, confused," properly "turns away in shame;" Latin trepit "he turns"). Technically, in rhetoric, "a figure of speech which consists in the use of a word or phrase in a sense other than that which is proper to it" [OED], "as when we call a stupid fellow an ass, or a shrewd man a fox" [Century Dictionary].
