The correct spelling of the phrase "wast sympathy" is actually "vast sympathy." The word "vast" is spelled with a "v" sound, like "van," as opposed to a "w" sound. The reason for this is because "v" and "w" are separate sounds in the English language, and "v" is the correct sound in this case. The IPA phonetic transcription for "vast sympathy" would be /væst ˈsɪmpəθi/. So next time you use this phrase, remember to spell it with a "v" instead of a "w"!
