How Do You Spell WAST PROFICIENT?
Pronunciation: [wɒst pɹəfˈɪʃənt] (IPA) 
The correct spelling of the word "wast proficient" is actually "was proficient." The error may have occurred due to a typographical mistake or perhaps confusion with the archaic use of "wast" as the second person singular past form of "be." The correct pronunciation of "was proficient" is /wʌz prəˈfɪʃənt/, with the stress on the second syllable of "proficient." It means that someone had a high level of skill or expertise in a particular area in the past.
