In a way that involves unwanted or uninvited interference or interruption.
She intrusively interrupted the meeting with her loud comments.
Intrusively → It is formed from "intrus-" (from Latin "intrudere", meaning to thrust in) and "-ively" (a suffix forming adverbs). The word "intrusively" describes the manner of thrusting in or entering without invitation or welcome.
Think of someone 'thrusting in' ('intrus-') where they are not wanted, and the '-ively' shows how they do it. This helps you remember that 'intrusively' means entering in an unwelcome manner.
