Something that happens before an official ceremony or event, especially one where someone is formally introduced to a position or role.
The preinaugural events included speeches and celebrations to mark the upcoming ceremony.
Preinaugural → It is formed from "pre-" (meaning before) and "inaugural" (from Latin "inauguralis", meaning pertaining to the inauguration). The word "preinaugural" refers to events or activities that occur before an inauguration.
Think of 'pre-' meaning before and 'inaugural' relating to the inauguration — so preinaugural describes things that happen before the official start.
