The correct spelling of "wast specific" is actually "was specific". The 't' in "wast" is a remnant of the Middle English form of the verb "to be" in the second person singular, which has largely fallen out of use. The correct pronunciation is /wɒs spɪˈsɪfɪk/. This phrase means that someone was very clear and precise in what they were saying or doing. It's important to pay attention to spelling and pronunciation to ensure effective communication.
