siglo
/ˈsiɡlo/ · A2 · noun · m
century
From Latin saeculum (an age) — same root as English secular
Latin saeculum meant a generation or age, later fixed at 100 years. It gave Spanish siglo, French siècle, and English secular (of this age, worldly). Sound hook: SEE-glo — you won't SEE a whole siglo GO by.
