'Channah' originates from Hebrew, specifically the word 'חַנָּה', where the root 'חָנַן' (ḥanan) meant 'to be gracious; to show favor'.

'Channah' changed from the Biblical Hebrew name 'Channah' and was rendered in Greek and Latin as 'Anna'; through Medieval and Biblical Latin and later English spellings ('Hanna', 'Hannah') the modern English forms 'Channah' and 'Hannah' arose as variant spellings.

Initially, it meant 'grace; favor', and as a personal name it has retained this core meaning into modern usage.
