Pronunciation
Forms
tenuis (neuter tenue, comparative tenuïor, superlative tenuissimus, adverb tenuiter); third-declension two-termination adjective[1]
Etymology
It is inherited from Proto-Italic *tn̥(a)u-, inherited from Proto-Indo-European *tn̥h₂-(e)u- (“thin”), a u-stem adjective made into an i-stem in Latin.[2][1] Cognate with Old Irish tanae (“thin”), Welsh teneu (“thin”), Sanskrit तनु (tanú, “thin”), Ancient Greek ταναός (tanaós, “long, stretched”) and English thin.[2][3] The root *tenh₂- may be an extended form of *ten- “to stretch”, as in teneō and tendō.[2][3]
Earliest recorded meaning
De Vaan dates it from Plautus,[2] who asks a girl whether she can spin a fine thread.[3][4] Köbler dates Plautus c. 250–184 BC.[5]
Semantic evolution
It meant fine, slender or thin, as of threads and membranes, thin between two surfaces, of bodies lean, of strips and paths narrow, of soil and drops fine, and of air rare.[3] Figuratively it meant slight, poor or of humble rank, and of style plain or simple.[6][4]
Döderlein groups it with exīlis and macer for leanness.[7] English took tenuis as a phonetic term, and formed English tenuous from it in the 1590s, attenuāre gave English attenuate.[1][6]
