Occasional verse is poetry written for a specific event, person, or public moment, such as a wedding, anniversary, birth, coronation, funeral, or civic celebration. Its main purpose is to mark the occasion, so it is often more direct and ceremonial than poetry written purely for personal reflection.
The term can cover both formal public poems and lighter private verses made for a particular gathering or tribute.
Example
For Anna and James on their wedding day:
Two voices, one shared road;
May every mile between you
be lighter for the other's hand.
