scatterbrain
A person who is very forgetful and easily distracted.
A scatterbrain is someone whose thoughts jump around so much that they frequently forget things or lose track of what they're doing. Picture a student who walks into their bedroom to get their math homework, sees a comic book on the desk, starts reading it, remembers they need to feed the dog, heads to the kitchen, notices their jacket on the floor, and completely forgets about the homework they came for in the first place.
Everyone has scatterbrained moments, especially when tired or overwhelmed. But a true scatterbrain lives this way regularly: losing their keys, forgetting appointments, starting three projects and finishing none. Their mind feels like a browser with fifty tabs open at once.
The word creates a vivid image: thoughts scattered like marbles rolling in different directions instead of organized in one place. You might call yourself scatterbrained after forgetting your lunch for the third time this week, or describe your distracted friend as a bit of a scatterbrain.
Being scatterbrained isn't the same as being unintelligent. Many creative, intelligent people have scatterbrained tendencies because their minds overflow with ideas and connections. The challenge comes when this mental scatteredness makes it hard to focus on important tasks or remember crucial details. Some people develop systems to manage their scatterbrained nature: writing everything down, setting phone reminders, or keeping important items in the exact same spot every single day.
