cold-hearted

The word 'cold-hearted' is a relatively modern English compound adjective, first appearing in the 16th century. It is formed by combining the literal concept of physical coldness ('cold') with the metaphorical seat of emotion ('heart'), and the adjectival suffix '-ed'. The logic is transparently metaphorical: just as a cold object lacks physical warmth, a cold-hearted person is perceived to lack emotional warmth, kindness, or empathy. This construction follows a common Germanic pattern for forming descriptive adjectives that characterize a person's nature, similar to 'warm-hearted' or 'hard-hearted'.

Structure: cold (low temperature) + heart (organ) + ed (adjective suffix) - cold: From Old English cald/ceald, of Germanic origin. In this compound, it functions metaphorically to mean 'lacking warmth of feeling'. - heart: From Old English heorte, of Germanic origin. In this compound, it represents the seat of emotions. - ed: A suffix of Germanic origin used to form adjectives from nouns, meaning 'having the characteristics of'.
