A person who attends an event, meeting, or gathering.
From 'attend' plus the French suffix -ee (from Latin -atus), which marks the recipient or undergoe of an action. This modern formation became standard in the 20th century.
The word 'attendee' is fascinating because it's one of the few modern additions to English that everyone immediately understood—when conferences exploded after WWII, we needed one word for 'people here.'
