ayer
/aˈʝeɾ/ · A2 · adv
yesterday
📅 ayer = a + yer, from Latin ad heri (at yesterday); heri also gave French hier
Latin heri meant yesterday; Spanish fused the preposition ad onto it, giving a-yer. Sound hook: ah-YAIR, like a YEAR ago, only much closer. Italian ieri and French hier are the same word without the a- prefix.
