Etymology

From Proto-Hellenic *tú, from Proto-Indo-European *túh₂. Cognates include Sanskrit त्वम् (tvam), Latin tū, Persian تو‎ (to) and Old English þū (English thou). The initial /s/ was spread to the nominative from oblique forms such as accusative σέ (sé) < *twé, where /s/ is the regular development of Proto-Indo-European *tw-.
