This is the meaning of intrusive I found online- "Something intrusive is getting in your face or invading your space. Nosey questions, a poke in the ribs, and a hovering mother are all intrusive."
I wonder if the word is somehow related to 'intruder?' I know an intruder is a person who intrudes in a place they are not wanted. Are these words related?
I thought it would help me remember the meaning of the word better.
