halfhearted

The word 'halfhearted' is a transparent English compound built from native Germanic elements. The literal, ancient sense of "half" as a "side" or "part" evolved to signify incompleteness. "Heart," a core concept in Old English for the physical organ and the metaphorical center of courage and feeling, combines with "half" to create a vivid image of only partial emotional or spiritual investment. The suffix "-ed" attaches to form an adjective, completing the modern meaning of an action performed with only a portion of one's zeal or commitment, logically extending from the literal "having only half one's heart in it."
