The correct spelling of the word "most ticking" is actually "mostic king". The reason for this unusual spelling is because the word comes from the Latin phrase "mosticum regem", which means "king of musts". In the transition from Latin to English, the middle consonant sounds of the two words merged together to form "tic". The correct pronunciation can be written in IPA phonetic transcription as /moʊstɪk kɪŋ/. So next time you come across the word "most ticking", remember its true spelling and origin!
