沉醉 literally combines 沉 (chén, 'to sink' or 'to submerge') and 醉 (zuì, 'to be drunk' or 'intoxicated'). Together, it describes a deep, immersive emotional state — not physical drunkenness, but figurative absorption, often in beauty, art, music, love, or nostalgia. It conveys being so captivated that one loses awareness of surroundings, similar to 'being spellbound' or 'lost in'. The word carries a positive, poetic nuance and is common in literary, descriptive, or reflective contexts.

While it can describe immersion in any compelling experience — such as nature, memory, or performance — it rarely appears in casual speech or technical writing. It’s frequently used with prepositions like 在…中 (‘in…’) or with objects indicating the source of fascination (e.g., 沉醉于音乐, ‘immersed in music’). The verb is intransitive but often takes 于 (yú) to mark the object of immersion, especially in formal or written Chinese.
