The correct spelling of the word is "wistful" and not "wast sympathetic." Wistful is spelled /ˈwɪstfʊl/ in IPA phonetic transcription. It means having or showing a feeling of vague or regretful longing. It is important to pay attention to the correct spelling of words to ensure effective communication. Incorrect spelling may lead to confusion and misunderstandings especially when dealing with formal documents. Therefore, it is advisable to always double-check the spelling of words before use.
