Etymology
Origin of infringe
First recorded in 1525–35; from Latin infringere “to break, weaken,” equivalent to in- in- 2 + -fringere, combining form of frangere “to break”; akin to break
Explanation
When you infringe on someone's space, time, or rights, you're getting involved in a way that is not cool. That's why, when you violate a copyright, you're said to infringe upon it. Infringe is almost always used with the prepositions "on" or "upon," as in, "if you infringe on my rights, I'll sue you." Nobody knows why that's the case. Our language is full of rules and traditions that just are the way they are. We call these phrases "idiomatic." To infringe "on" or "upon" something is one of those. You don't infringe "into" someone's conversation. You infringe "upon" it. Case closed.
