一天到晚

• 拼音: yī tiān dào wǎn
• 汉字拆解: 一 = one (a whole); 天 = 大 + 一 (great + one — heaven, day); 到 = 至 + 刀 (arriving at a point); 晚 = 日 + 免 (sun + retreat — evening)

含义

All day long; from morning till night; the whole day through. Emphasises that an activity or state persists throughout the entire waking day without interruption.

Often carries a mildly exasperated or critical undertone — the speaker implies the activity is excessive or tiresome: 一天到晚打游戏 (gaming all day long), 一天到晚抱怨 (complaining the whole day). Synonymous in basic sense with 整天 but more emphatic through the explicit 到晚 framing, which marks the full arc from start to end of day.

例句
