Etymology: Latin "avunculus" meant "maternal uncle," the brother of one's mother, and it was a deliberately affectionate-sounding word. It is a diminutive formed from "avus," grandfather, so the literal sense is roughly "little grandfather." The Romans seem to have treated the mother's brother as a special figure, somewhat like a second father, and the diminutive ending marks that closeness rather than any lesser status. The word passed into English without much change in form, but it stayed firmly in Latin and scholarly contexts. English speakers mostly reached for "maternal uncle" instead, and "avuncular," an adjective meaning kindly and uncle-like, came from the same root and is the form most people still meet.
