σύγχρονος

Etymology: From Ancient Greek σύγχρονος, composed of σύν (syn-, meaning 'with' or 'together') + χρόνος (chronos, meaning 'time'). The prefix σύν is cognate with English 'syn-' found in words like 'synchronize', 'synthesis', and 'symphony'. The root χρόνος gives us English words like 'chronology', 'chronic', and 'chronometer'. The literal meaning is 'with time' or 'of the same time', which explains both its temporal meanings (contemporary, modern) and its sense of simultaneity (concurrent, synchronous).
