clout: [OE] In Old English, a clout was a patch of cloth put over a hole to mend it. Hence in due course it came to be used simply for a ‘piece of cloth’, and by further extension for a ‘garment’ (as in ‘Ne’er cast a clout till May be out’). However, the reason for its colloquial application to ‘hit, blow’, which dates from the 14th century, is not known, and indeed this may be an entirely different word. As for the word’s ultimate antecedents, it probably comes, along with cleat, clot, cluster, and clutter, from a prehistoric Germanic base *klut-, *kleut-, *klaut-.
=> cleat, clot, cluster, clutter
clout (n.)youdaoicibaDictYouDict
Old English clut "lump of something," also "patch of cloth put over a hole to mend it," from Proto-Germanic *klutaz (cognates: Old Norse klute "kerchief," Danish klud "rag, tatter," Frisian klut "lump," Dutch kluit "clod, lump"); perhaps related to clot (v.).

In later use "a handkerchief," also "a woman's sanitary napkin." Sense of "a blow" is from c. 1400 early 14c., from the verb. Sense of "personal influence" is 1958, on the notion of "punch, force."
muzzle (n.)youdaoicibaDictYouDict
late 14c., "device put over an animal's mouth to stop it from biting, eating, or rooting," from Old French musel "muzzle," also "snout, nose" (12c., Modern French museau), from muse "muzzle," from Gallo-Roman *musa "snout" (source also of Provençal mus, Old Spanish mus, Italian muso), of unknown origin, possibly related to Latin morsus "bite" (but OED finds "serious difficulties" with this). Meaning "projecting part of the head of an animal" is from early 15c. in English; sense of "open end of a firearm" first recorded 1560s.
priest (n.)youdaoicibaDictYouDict
Old English preost probably shortened from the older Germanic form represented by Old Saxon and Old High German prestar, Old Frisian prestere, all from Vulgar Latin *prester "priest," from Late Latin presbyter "presbyter, elder," from Greek presbyteros (see Presbyterian).

An alternative theory (to account for the -eo- of the Old English word) makes it cognate with Old High German priast, prest, from Vulgar Latin *prevost "one put over others," from Latin praepositus "person placed in charge," from past participle of praeponere (see provost). In Old Testament sense, a translation of Hebrew kohen, Greek hiereus, Latin sacerdos.
