There is actually no word called "worster" in the English language. The correct comparative form of the adjective "bad" is "worse". The reason why some people might use "worster" is perhaps due to their accent or their lack of knowledge of the language. The International Phonetic Alphabet transcription for "worster" would be /ˈwɔːstər/ or /ˈwɜːstər/. It is important to learn and use correct spellings in written and spoken English to avoid confusion and ambiguity.
"Worster" is a dialectal variant and nonstandard form of the word "worse." It is primarily employed as an adverb or adjective to convey a comparative degree of badness, inferiority, or unfavorable quality in comparison to something else. While not formally recognized in standard English, "worster" is often used as an extension or exaggeration of the word "worse" to emphasize or intensify the negative aspect being described.
As an adverb, "worster" usually modifies a verb or an adjective, indicating that the action or quality being referred to is more unfavorable or of a lower standard than something else. For example, one might say "He performed worster in his second attempt," to convey that the individual's performance was even more unsatisfactory in comparison to his previous attempt.
When used as an adjective, "worster" describes a noun or pronoun as being of poorer quality, less desirable, or more unsatisfactory than another item or alternative. For instance, one might say "This season's harvest is worster than last year's," meaning that the current crop yield is noticeably inferior or produces a less favorable outcome compared to the previous year.
It should be noted that although "worster" is occasionally employed informally in certain dialects or colloquial speech, it is nonstandard and not universally recognized in formal or standard English usage.
The word "worster" does not have its own independent etymology because it is not a standard English word. It appears to be a non-standard variation or misspelling of the word "worse". The word "worse" can be traced back to the Old English word "wyrsa", which means "more bad" or "inferior". However, "worster" itself does not have established origins or a defined etymology. It is likely an incorrect form or a colloquial adaptation.
