The spelling of the word "wast uptight" seems confusing at first glance, but it actually follows the rules of English phonetics. "Wast" is pronounced with a short "a" sound, as in "cat," and the "s" is silent. "Uptight" is spelled phonetically, with a clear "u" sound as in "put," a "p" sound, and a "t" sound. The word means excessively tense or nervous, and its phonetic spelling makes it easy to understand and pronounce correctly.
