The word "wert touch" may seem confusing, but its spelling can be explained with the use of IPA phonetic transcription. The "w" sound at the beginning of the word is represented with /w/, followed by the vowel sound /ɛ/ as in "bed". The "r" sound is then represented with /r/, followed by the consonant blend "tch" which is pronounced as /tʃ/. Finally, the final consonant sound is represented with /ʃ/ as in "shoe". So, the correct spelling of the word "wert touch" is /wɛrt tʃʌʃ/.
There seems to be a misunderstanding or error in the phrase wert touch. Wert is an archaic form of the word were, which means was or were. However, touch doesn't seem to have any connection to wert in this context. Touch is derived from the Old French word tochier, meaning to touch, which can be traced back to the Latin word toccare.
