Morphology

lightning + arrester

The noun is transparently built from 'lightning' (electrical discharge) + 'arrester' (a device that stops or limits), so its meaning as a device that stops or protects against lightning/sudden surges is directly inferable. Although somewhat technical, the compound follows regular noun–noun composition and similar formations exist in many languages, so a B1 learner who knows both constituents should understand it.

Etymology

The compound noun lightning arrester comes from the image of a small device that catches storm electricity and gives it a safe path to the ground; here lightning is the strong electric strike and arrester means something that 'stops' or 'holds back'. That's why a lightning arrester means a device that 'protects' power lines and equipment by sending dangerous electricity into the earth instead of into the building.
