Most addleheaded may be used to describe someone who is extremely stupid or confused beyond belief. Synonyms for this term could include: dim-witted, unintelligent, foolish, scatterbrained, absent-minded, clueless, ditsy, brainless, airheaded, doltish, and thick-headed. These words describe an individual who may struggle with basic tasks, lacks common sense, and seems to be lost in thought most of the time. Most addleheaded individuals may also exhibit forgetfulness, disorganization, and difficulty with decision-making. Using these synonyms instead of the somewhat offensive term "addleheaded" can help avoid hurting feelings while still conveying the same meaning.
