How it's used

Focuses strictly on the automatic acquisition of a role due to holding another position. Unlike the common adverbial use meaning of course, this specific usage functions as a modifier for titles or roles. It implies that the person holds the second position simply because they occupy the first one.

Examples

He is the president, so he is an ex officio member of the committee.
The principal is an ex officio school manager and does not need to be elected separately.

Common phrases

ex officio school manager

Common mistake

Learners often confuse this with the common adverbial meaning of course or naturally, leading to awkward phrasing when trying to describe official roles. Always ensure it is used as a modifier for a noun representing a position or status.
