适时

• ピンイン: shì shí
• 漢字の分解: 适 = 辶 + 啇 (fitting, appropriate — moving toward what suits); 时 = 日 + 寺 (time — the sun's position at the temple indicating the hour)

意味

適時に（ちょうどよい時に）

Implies not merely being prompt, but choosing the optimal moment for an action — a moment when conditions are most favourable. Common collocations: 适时介入 (to intervene at the right time), 适时调整 (to adjust at the right moment), 适时出台 (to introduce at an opportune time), 适时播种 (to sow at the right time). Carries a strong connotation of strategic timing and situational awareness. Distinct from 及时 (timely — in time, without delay) which emphasises promptness, whereas 适时 emphasises optimality of moment.

正しい言い方

• 优秀的危机公关专家深知，在舆论压力最为集中的时间节点上适时发声，往往比事后数倍的解释和澄清更能有效扭转公众认知和重建品牌信誉。(Excellent crisis communications specialists know well that speaking out at the right moment — when public opinion pressure is at its most concentrated — is often far more effective at reversing public perception and rebuilding brand credibility than several times the amount of explanation and clarification after the fact.)
• 经济学家建议，中央银行在通胀压力开始显现但尚未失控之际适时加息，可以在维持经济增长动能的同时有效抑制价格水平的持续上行。(Economists advise that if the central bank raises interest rates at the right time — when inflationary pressure begins to emerge but has not yet lost control — it can effectively restrain the continued upward movement of price levels while maintaining the momentum of economic growth.)

避ける言い方

• 适时 when simply meaning 'quickly' or 'without delay' — use 及时 (in time, promptly); 适时 is about choosing the optimal moment, not merely acting quickly; using 适时 where 及时 is intended can imply an unintended strategic calculation where none exists
