ζευγάρι

Etymology: From Ancient Greek ζεῦγος (zeûgos, 'a pair, team'), which derives from the verb ζεύγνυμι (zeúgnumi, 'to yoke, join together'). This shares the same Indo-European root as the English word 'yoke'. The concept of joining or pairing is fundamental to the word's meaning, reflecting how two things or people are connected or belong together.
