Gol he, also called choṭī he, is one of the two variants of the Arabic letter he/hāʾ (ه) that are in use in the Urdu alphabet, the other variant being the do-cas͟hmī he (ھ), also called hā-'e-mak͟hlūt. The letter is named for its shape in the isolated form, gol meaning "round" in Hindustani, to distinguish it from the do-cas͟hmī he, which is really a calligraphic variant of the "two-eyed" regular he in the medial position (ﻬ). Its various non-isolated forms originated in the Nastaʿlīq script or calligraphic hand, though various zigzag (medial) and hook (final) forms of hāʾ have existed before the script was developed.
