velveteen (n.)

early 14c., probably from Old Provençal veluet, from Vulgar Latin *villutittus, diminutive of Vulgar Latin *villutus "velvet," literally "shaggy cloth," from Latin villus "shaggy hair, nap of cloth, tuft of hair," probably a dialectal variant of vellus "fleece," from PIE *wel-no-, suffixed form of *uelh- "to strike" (see svelte).

also -in, adjectival word-forming element, Middle English, from Old French -in/-ine, or directly from Latin suffix -inus/-ina/-inum "of, like," forming adjectives and derived nouns, as in divinus, feminus, caninus; from PIE adjectival suffix *-no- (see -en (2)).

The Latin suffix is cognate with Greek -inos/-ine/-inon, and in some modern scientific words the element is from Greek. Added to names, it meant "of or pertaining to, of the nature of" (Florentinus), and so it also was commonly used in forming Roman proper names, originally appellatives (Augustinus, Constantinus, Justinus, etc.) and its descendants in Romanic languages continued active in name-forming. The Latin fem. form, -ina, was used in forming abstracts (doctrina, medicina). Relics of the attempt to continue a distinction between Latin -ina and -inus account for the English hesitation in spelling between -in and -ine.

"fabric having a glossy surface resembling satin," 1835, a variant of satin (q.v.), perhaps influenced by velveteen, where the ending is a variant of -ine (1).
