 Nicknames such as "Ai", "Yee", and "Sam" designated children as 'one', 'two', and 'three'.Later, in the Ayutthaya and Rattanakosin periods, children began to be named for physical attributes, such as "Daeng" ('red') or "Uan" ('fat') or for desirable items such as "Thong" ('gold').Conversely, unflattering nicknames such as "Mah" ('dog'), "Moo" ('pig'), or "Gop" ('frog') were employed to keep malign spirits from coveting the child.
