時期
じき · jiki · JLPT N3 · noun
time
📅 時期 = time (時) + period (期): a stretch of time, a season
時 is the time kanji from 時間 (jikan); 期 is the period kanji from 期間 (kikan) and 学期 (school term). Sound hook: ji-ki takes the ji of jikan and the ki of kikan. Put together, they name a particular period or season for something.
期 — 其 (phonetic) + 月 (moon/time)
期 is a phono-semantic compound. The right side 月 (moon) signals meaning, since lunar cycles marked fixed time periods in ancient China. The left side 其 supplies the sound. Together it points to a set time, period, or appointed date — meanings still carried today in words like 期间 and 日期.
