湿気
しっけ · shikke · JLPT N3 · noun
dampness
💧 湿気 = damp (湿) + air (気): damp air is humidity
湿 means wet or damp, and 気 means air or atmosphere, as in 天気 (weather) and 空気 (air). Shitsu + ke contracts to shikke with a doubled k. Sound hook: a sticky, humid day leaves you feeling shikke-icky.
湿 — water 氵 + 㬎 (phonetic, 'visible')
湿 originally depicted dampness, combining the water radical 氵 with 㬎, which suggests sun shining on silk threads being dried. The water component carries the meaning 'wet/damp,' while 㬎 hints at the pronunciation. Modern simplified form 湿 replaced traditional 濕.

湿 means wet and 気 means air or energy, so 湿気 is the damp feeling in the air. Say 'shikki' like 'ship' + 'key': a ship that gets a key wet with dampness.
