A person who is loved or cherished, especially a romantic partner. Can also be used as a term of endearment for someone dear.
From Middle English swete herte, combining 'sweet' (Old English swēte) and 'heart' (Old English heorte). The compound emerged in the 14th century as a metaphorical expression linking the sweetness of taste with emotional affection. The term evolved from literal 'sweet heart' to a single word denoting beloved persons.
The word 'sweetheart' beautifully demonstrates how English creates intimate vocabulary by combining sensory experiences with body parts - we literally taste love through the heart. Interestingly, similar compounds exist across many languages, suggesting this metaphorical connection between sweetness and affection is nearly universal in human experience.
Historically used more toward women as diminutive term of endearment; carries paternalistic associations when applied asymmetrically across genders.
Use symmetrically or avoid in formal/professional contexts where it risks infantilizing.
