Etymology

PIE word *ḱḗr From Middle English herte, from Old English heorte (“heart”), from Proto-West Germanic hertā, from Proto-Germanic hertô (“heart”), from Proto-Indo-European *ḱérd (“heart”). Doublet of cardia; see also core. Most of the modern figurative senses (such as passion or compassion, spirit, inmost feelings, especially love, affection, and courage) were present in Old English. However, the meaning “center” dates from the early 14th century. The verb sense “to love” is from the 1977 I ❤ NY advertising campaign. Notes on spelling The spelling ⟨ear⟩ for /ɑː(ɹ)/ is paralleled by hearken and hearth, but is problematics since a Early Modern variant with /ɛːr/ can be posited for those words, but not heart. Perhaps it represents Middle Scots hart /hɛːrt/ (reflecting the Scots lengthening of /a/ before /r/ then a consonant, then the early actuation of the Great Vowel Shift in Scots) or a parallel development in Northern England. Alternatively, a back-spelling by speakers of dialects where preconsonantal /ɛːr/ was shortened early, allowing it to undergo the late Middle English lowering to /ar/ (reflected in forms such as larn "learn") is possible.
