# aitch

> English word · Noun · IPA /ˈeɪt͡ʃ/

## Definitions
1. The name of the Latin script letter H/h.

## Etymology
From Middle English ache, borrowed from Old French ache, from Vulgar Latin *acca. The source is unclear, but may descend from the vowelless alphabetic sequence ha ka 'H, K' (becoming [aka] when the [h] ceased to be pronounced), as K had low frequency in Late Latin. Doublet of ecchi.
