IPA: /ædˈvaʊzən/
KK: /ædˈvaʊzən/
A legal right in English church law that allows a person or group to choose someone to fill a vacant church position.
The church's advowson allowed them to nominate a new vicar when the position became vacant.
Advowson is derived from the Old French 'avocacion' (meaning the act of calling or summoning) and the Latin 'advocatio' (meaning the act of calling to one's aid). The word refers to the right of presenting a nominee to a church benefice or position.
Think of 'calling' someone to a position — 'avocacion' means to summon, and 'advowson' is about the right to nominate someone for a church role.
