Not clear or sharp; lacking concentration or direction.
Her thoughts were unfocused during the meeting, making it hard for her to contribute.
Unfocused → It is formed from "un-" (meaning not) and "focused" (from Latin "focus", meaning hearth or center). The word "unfocused" means not centered or lacking concentration.
Think of 'not' ('un-') being added to 'centered' ('focused') — that's why unfocused means lacking concentration.
