The spelling of the phrase "wast convenient" may be confusing to some English language learners as it contains an archaic verb form and an outdated spelling of a common word. The first word, "wast," is the second person singular past tense of the verb "to be" in Early Modern English. The second word, "convenient," is spelled with an additional "st" at the end, which was a common spelling in Middle English. The phonetic transcription of this phrase would be /wɑst kənˈvinjənt/.
