'halakhic' originates from Hebrew, specifically the word 'halakhah' (הלכה), where the root 'halakh' meant 'to walk' or 'to go'.

'halakhic' changed from the Hebrew noun 'halakhah' (meaning the way or conduct) and entered English via rabbinic literature and scholarly usage (including Yiddish and modern academic works), eventually becoming the English adjective 'halakhic'.

Initially it referred to a 'way' or 'manner' (from the verb 'to walk/go'), then to the body of Jewish legal rulings called 'halakhah', and it now means 'relating to Halakha' in English.
