gangling (adj.)[gangling 词源字典]: "long and loose-jointed," by 1812, from Scottish and Northern English gang (v.) "to walk, go," which is a survival of Old English gangan, which is related to gang (n.). The form of the word is that of a present-participle adjective from a frequentative verb (as in fondling, trampling), but no intermediate forms are known. The sense extension would seem to be via some notion involving looseness in walking.
GANGLING. Tall, slender, delicate, generally applied to plants. Warw. [James O. Halliwell, "A Dictionary of Archaic and Provincial Words," 1846]

Southron (n.): "inhabitant of the southern part of a country," late 15c., variant (originally Scottish and northern English) of southren (late 14c.), on analogy of Briton, Saxon, from Old English suðerne or Old Norse suðrænn "southern" (see southern). Popularized in English by Jane Porter's enormously popular historical novel "Scottish Chiefs" (1810), and adopted in U.S. by many in the Southern states. She also used it as an adjective. Old English had suðmann "Southman."
But the moment I heard he was in arms, I grasped at the opportunity of avenging my country, and of trampling on the proud heart of the Southron villain who had dared to inflict disgrace upon the cheek of Roger Kirkpatrick. ["Scottish Chiefs"]
thresh (v.): Old English þrescan, þerscan, "to beat, sift grain by trampling or beating," from Proto-Germanic *threskan "to thresh," originally "to tread, to stamp noisily" (cognates: Middle Dutch derschen, Dutch dorschen, Old High German dreskan, German dreschen, Old Norse þreskja, Swedish tröska, Gothic þriskan), from PIE root *tere- (1) "to rub, turn" (see throw (v.)).

The basic notion is of men or oxen treading out wheat; later, with the advent of the flail, the word acquired its modern extended sense of "to knock, beat, strike." The original Germanic sense is suggested by the use of the word in Romanic languages that borrowed it, such as Italian trescare "to prance," Old French treschier "to dance," Spanish triscar "to stamp the feet."
trample (v.): late 14c., "to walk heavily," frequentative form of tramp (v.). Transitive sense "beat down by continuously treading on" is from mid-15c. Related: Trampled; trampling. As a noun from c. 1600.
