TIL of ablaut reduplication, an unwritten English rule that makes "tick-tock" sound normal, but not "tock-tick". When repeating words, the first vowel is always an I, then A or O. "Chit chat" not "chat chit"; "ping pong" not "pong ping", etc. It's unclear why this rule exists, but it's never broken
