The word "heckart" is an unusual spelling of the word "haggard". The spelling likely originated from a dialectal pronunciation of the word, which emphasized the "k" sound in the middle of the word. In IPA phonetic transcription, the word is spelled /ˈhɛkɑrt/, with the stressed syllable being pronounced with a short "e" sound, and the "k" being emphasized with a slight pause in pronunciation. While the spelling of the word may be uncommon, its pronunciation is still recognizable to many English speakers.
