Etymology : The Latin verbs tenu?re ?to make thin, slender, meager; rarefy? and its compound attenu?re ?to make thin or weak; weaken, diminish? both occur in classical authors and are just about synonymous (attenu?re seems to have slightly more emphasis on making weak or feeble). The root word is the Latin adjective tenuis ?thin,? from the very common Proto-Indo-European root ten- ?stretch? (tenuis thus means ?stretched out?), appearing in Latin tendere ?to stretch? (and source of English tend), Latin tener ?soft, delicate? (the source, through French of English tender) and Germanic (English) thin. Attenuate entered English in the 16th century.
