A state or condition of being inclined to laughter; the quality or habit of laughing frequently.
From the adjective 'gelose' with the noun-forming suffix '-ie' or '-y'. An obsolete or rare medical term derived from Greek 'gelos'.
Gelosie is so rare that it barely appears in English texts, but it shows how systematically people created medical terminology—if you could have 'melancholia' (sad humors), you could have 'gelosie' (laughing humors)!
