The correct spelling of the word "wert abhorrent" is actually "were abhorrent." The reason for the confusion may be because "wert" is an archaic form of the word "were," which means "past tense of be." The correct pronunciation of "were abhorrent" is /wər əbˈhɔrənt/. The IPA phonetic transcription helps to accurately represent the sounds in the word, with the "ə" representing the schwa sound and the "ˈ" indicating the primary stress on the second syllable.
The phrase "wert abhorrent" is not a word but a combination of words. "Wert" is an archaic form of the verb "to be" in the second person singular past tense in old English, while "abhorrent" is an adjective that comes from the Latin word "abhorrens", which means "shrink back in horror". "Abhorrent" entered the English language in the late 16th century.
