IPA: //ˌnɒnəˈtɛndər//
KK: /nɑnəˈtɛndər/
A person who does not go to an event or gathering.
The nonattender missed the important meeting and was unaware of the updates.
Nonattender → It is formed from "non-" (meaning not) and "attender" (from the verb "attend", which comes from Latin "attendere", meaning to stretch toward or pay attention). The word "nonattender" refers to someone who does not attend or is not present at an event or gathering.
Think of 'not' ('non-') being combined with 'paying attention' ('attendere') to remember that a nonattender is someone who does not show up or pay attention to an event.
