impinge

im-PINJ/ɪmˈpɪndʒ/

To press or strike against something's boundary.

The overgrown hedge impinges on the footpath, narrowing the wheelchair user's passage.

A neighbor's overgrown hedge intrudes far across a narrow public footpath, forcing an adult wheelchair user to pause at the narrowed passage while a companion looks at the obstructing branches.

Etymology

“Into” combined with “fix or fasten” produced the sense “drive into, strike against.” That physical contact became figurative encroachment: affecting something by pressing upon its space or limits.
