aitch v Haitch

The name aitch might be a sign of high education in some circles, but is itself an example of H-dropping. Deriving from medieval French hache or “axe” (hatchet and hashtag are relatives), it also arrived in English H-less (like humble and herb).

It’s a curious letter name being, as the Oxford English Dictionary describes, “so remote from any connection with the sound”. In fact there’s solid evidence supporting haitch as the better option.
