"Wert of assistance" is a commonly misspelled phrase. The correct spelling uses the archaic second person singular past tense of "be" followed by "of assistance." The IPA phonetic transcription for "wert" is /wɜrt/, which conveys the pronunciation of the word as "wuhrt." The spelling may be confusing for those less familiar with archaic English language, but it is important to use correct spelling and grammar to maintain clear communication.
