时间 (shí jiān) is a fundamental noun meaning 'time' in the abstract sense — not a specific clock reading, but the general concept of duration, chronology, or temporal existence. The first character 时 (shí) means 'hour', 'moment', or 'season', and carries connotations of a measurable unit or point in time; the second character 间 (jiān) means 'interval', 'space between', or 'period', emphasizing the stretch or gap between events. Together, they form a compound that expresses time as a continuous, flowing dimension — used when discussing schedules, deadlines, life stages, historical periods, or philosophical reflections on temporality.

This word appears frequently in both spoken and written Chinese: in questions like '现在几点？' (What time is it?), it’s often replaced by 点 (diǎn); but for broader contexts — such as '没有时间', '浪费时间', or '宝贵的时间' — 时间 is the standard, neutral, and unmarked term. It does not imply urgency or emotion by itself, making it versatile across formal reports, casual conversation, and literary texts.
