Correct spelling for the English word "Worser" is [wˈɜːsə], [wˈɜːsə], [w_ˈɜː_s_ə] (IPA phonetic alphabet).
The word worser is formed by adding the suffix -er to the word worse, which is the comparative form of the adjective bad. The etymology of worse can be traced back to its Old English root wiersa (from the Proto-Germanic *wers-), meaning more evil or more unfavorable. Over time, worse developed into its current form, and the addition of the -er suffix creates worser as a comparative form. However, it's essential to note that while worser has been used historically, it is considered non-standard English. The standard comparative form of bad is worse.
