half-hearted
UK: ˌhɑːf ˈhɑːtɪd | US: ˌhæf ˈhɑːrtɪd
adj. lacking enthusiasm or effort; unenthusiastic or indifferent.
The word "half-hearted" combines "half," meaning partial or incomplete, with "heart," symbolizing core emotion or commitment. The suffix "-ed" turns it into an adjective. Historically, the heart has been metaphorically linked to passion and sincerity (e.g., "wholehearted"). "Half-hearted" emerged in the 17th century to describe actions or attitudes lacking full emotional investment, reflecting a literal "half-measure" of dedication.
