"Half-wits" is a derogatory term used to describe individuals who appear to lack intelligence or common sense. However, there are more polite and sensitive synonyms that can be used instead. These include terms such as "intellectually challenged," "simple-minded," "slow-witted," "mentally disabled," "cognitively impaired," "learning disabled," "developmentally delayed," and "special needs." It is important to remember that using derogatory language or offensive labels can be hurtful to individuals and their loved ones. Therefore, using respectful and thoughtful language is essential to promote inclusivity and respect for all.
