Preposition after adjective

preoccupied + preposition

Preoccupied is most commonly followed by with. Other prepositions can appear in specific contexts but are less typical as direct complements.

Quick answer

Which preposition follows preoccupied?

Use preoccupied with for being mentally focused on something. Preoccupied by also occurs, especially when something captures attention. Preoccupied about is uncommon, and preoccupied in usually introduces a larger activity or situation rather than the adjective complement itself.

She was preoccupied with work deadlines.
He seemed preoccupied by the news.
They were preoccupied with financial problems.
