The spelling of "wast ears in" may seem unusual, but it is simply an archaic way of writing "waste ears in". The word "waste" means to spend or use something carelessly, while "ears in" means to listen carefully or pay attention. The pronunciation is /weɪst ɪərz ɪn/, with the stress on the first syllable of "waste". It's important to note that while this spelling may have been used in the past, it is not commonly used in modern English.
