noun
jealousy; envy; feeling of envy

Refers to admiration or envy without the negative, resentful nuance often present in 嫉妬心.
Compound of 嫉妬 (しっと, 'jealousy') and 心 (しん, 'heart/mind'). The exact historical derivation is uncertain, but the combination straightforwardly means 'jealous heart' or 'feeling of jealousy'.
