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