The spelling of the word "hightest" is incorrect. The correct spelling is "highest", with the IPA transcription /ˈhaɪ.ɪst/. The word is made up of two syllables - "high" and "est". The first syllable is pronounced with the vowel sound /aɪ/, as in "eye", and the second syllable is pronounced with a short vowel sound /ɪ/, as in "sit". The correct spelling and pronunciation of words is important for clear communication and effective writing.
The word "hightest" is the superlative form of the verb "hight", which is an archaic form of the verb "to be called" or "to be named". It comes from Middle English "highte", which derived from the Old English word "hatan", meaning "to command" or "to call". In Old English, it was conjugated as "he hātte" (he is called), and over time evolved into "hight" in the present tense for the third person singular. "Hightest" is the superlative form, meaning "to be named the highest" or "to be called the highest". However, it is predominantly used in older or poetic contexts today.
