深情 (shēn qíng) literally combines 深 (shēn), meaning 'deep' or 'profound', and 情 (qíng), meaning 'feeling', 'emotion', or 'affection'. Together, they convey a rich, sincere, and deeply felt emotional state — most often love, devotion, gratitude, or nostalgia. It emphasizes the intensity and authenticity of feeling rather than its duration or outward expression.

This word is commonly used in literary, poetic, or heartfelt contexts: describing a lover’s gaze, a parent’s sacrifice, an artist’s tribute, or a farewell speech. It appears frequently in song lyrics, film subtitles, and formal speeches. While it can function as a noun ('deep affection') or adjective ('heartfelt'), it rarely stands alone without context — usually modifying nouns like 眼神 (gaze), 歌声 (voice/song), or 怀念 (longing). It carries warmth and dignity, never casualness or irony.
