H with stroke

(Redirected from Ħ)

Ħ (minuscule: ħ) is a letter of the Latin alphabet, derived from H with the addition of a bar. It is used in Maltese for a voiceless pharyngeal fricative consonant (corresponding to the letter heth of Semitic abjads: Arabic: ح, Hebrew: ח). Lowercase ħ is used in the International Phonetic Alphabet for the same sound. It was used for this sound in the 1556 work of Pérez de Ayala, slightly modified from Pedro de Alcalá's Vocabulary.[1]

Letter "Ħ"
Perez de Ayala's version of Lord Prayer in Spanish and Andalusian Arabic (1556), compare to Maltese:
ħobżna ta' kuljum agħtihulna llum.

In Unicode, the special character ℏ (U+210F), represents the reduced Planck constant of quantum mechanics.[2] In this context, it is pronounced "h-bar".

The lowercase resembles the Cyrillic letter Tshe (ћ), or the astronomical symbol of Saturn (♄).

A white uppercase Ħ on a red square was the logo of Heritage Malta until 2022.[3]

It is used as the symbol for Hedera Hashgraph's native cryptocurrency, HBAR.[4]
