钟情 is a verb-object compound (离合词) meaning 'to be deeply in love with' or 'to have a strong passion for'. It often appears in the pattern 钟情于 + object (e.g., 钟情于艺术), or directly with a person (钟情某人). The object of affection can be romantic or abstract (e.g., art, literature). As a v.o. structure, it can be separated to insert measure words or duration, though such separations are rare in daily speech — you may hear 钟过一次情 'have fallen in love once'. This word carries a literary, slightly classical tone.
