What does scatterbrain mean?
Scatterbrain is an informal noun for a person whose attention, memory, or organization is easily disrupted. It typically suggests that someone forgets appointments, misplaces belongings, or becomes distracted rather than that they are deliberately careless or irresponsible. The term often carries a mildly disparaging tone, but in friendly contexts it can be affectionate, as when a family calls a loved one a lovable scatterbrain. It is commonly associated with everyday forgetfulness, though it can also describe someone whose mind is always full of unrelated ideas and interests. The related adjective scatterbrained is often more useful when describing behavior: for example, a scatterbrained driver may leave without a destination. Both forms are familiar in British and American English but are more characteristic of casual speech than formal writing.
