O-hook in the context of "He (letter)"

He is the fifth letter of the Semitic abjads, including Phoenician hē 𐤄, Hebrew hē ה‎, Aramaic hē 𐡄, Syriac hē ܗ, and Arabic hāʾ ه‎. It is also related to the Ancient North Arabian 𐪀‎‎‎, South Arabian 𐩠, and Ge'ez ሀ. Its sound value is the voiceless glottal fricative ([h]).

The proto-Canaanite letter gave rise to the Greek Epsilon Ε ε, Etruscan 𐌄, Latin E, Ë and Ɛ, and Cyrillic Е, Ё, Є, Э, and Ҩ. He, like all Phoenician letters, represented a consonant, but the Latin, Greek and Cyrillic equivalents have all come to represent vowel sounds.
