時計
とけい · tokei · JLPT N5 · noun
watch
⌚🕰️ 時計 = time + measure: the thing that measures time
時 means time or hour, and 計 means to measure or count (as in 計画 plan, 合計 total). The reading tokei is irregular: 時 is normally ji or toki, so treat to-kei as a set piece. Sound hook: a clock goes tick-tock, tokei.
