The purpose of this study is twofold: One is to present and characterize the English metaphors and metonymies of heart+sadness starting from the metonymy of heart-sickness and the metaphor of sadness in K?vecses (2000) The other is to show their various complexes based on Ruiz de Mendoza & Galera-Masegosa (2011). Heart+sadness metonymies are connected in terms of cause and effect. Most source domains of the sadness metaphor are found in heart+sadness except for coldness, darkness and insanity. Some heart+sadness, whose source domains are the opponent, the social superior, the fluid, the living organism, the captive animal, and natural force, are conceptually stable in that the conceptualization of [HEART] is definite and its relation with sadness is clear; Some others, whose source domains are physical force, sickness, and lack of life, are rather flexible in that the conceptualization of [HEART] is not definite, or its relation with sadness is not clear. Complexes of heart+sadness expressions are diverse with chained metonymy, metonymy within metaphor, chained metaphor, and metaphor amalgam.
