καθένας

Etymology: Derived from the Ancient Greek 'καθ' ἕνα' (kath' hena), which literally means 'according to one' or 'by one'. It combines 'κατά' (kata, meaning 'according to', 'by', 'down') and 'ἕνα' (hena, the accusative form of 'εἷς', meaning 'one'). This formation reflects the distributive sense of the pronoun, emphasizing individuality within a group.
