From Late Middle English intens, intense (“ardent, fervent; extreme, great, intense”), borrowed from Old French intense (modern French intense), or directly from its etymon Latin intēnsus (“strained, stretched tight; intense; attentive; violent; (rare) eager, intent”), the perfect passive participle of intendō (“to stretch out, strain”), from in- (prefix meaning ‘in, inside, within’) + tendō (“to extend, stretch”) (ultimately from Proto-Indo-European *tend- (“to extend, stretch”)).
