Correct spelling for the English word "caltiff" is [kˈɒltɪf], [kˈɒltɪf], [k_ˈɒ_l_t_ɪ_f] (IPA phonetic alphabet).
The word "caltiff" has an intricate etymology that has evolved over time. Its origins can be traced back to the Old English word "ceald-heort" or "ceald-heard", which meant "cold-hearted" or "hard-hearted". The word "ceald" (cold) referred to an absence of warmth or emotion, while "heort" (heart) denoted the seat of emotions or feelings.
Over the centuries, the term underwent changes in pronunciation and spelling. In Middle English, it transformed into "cauld-hert", retaining its meaning of being cold-hearted or unfeeling. Eventually, it morphed into "cald-heart", "cauld-heart", and finally, "caltiff".
"Caltiff" is predominantly used in Scots English, where it still carries the connotation of someone who is unfeeling, callous, or lacking in compassion.
