The spelling of the word "wast on to" may seem peculiar, but it is a valid construction in many dialects of English. In IPA phonetic transcription, it is pronounced as /wɑst ɒntu/. The word "wast" is the archaic second person singular past tense of "be," while "on to" means "onto." Therefore, "wast on to" can be translated to "you were onto" in modern English. Although it may be confusing at first, the spelling of "wast on to" is a fascinating example of the evolution of the English language.
