Airstrip → It is formed from "air" (from Old English "aer", meaning the atmosphere or sky) and "strip" (from Old English "strippa", meaning a narrow piece or strip of land). The word "airstrip" refers to a narrow piece of land designated for aircraft to take off and land in the atmosphere.
Think of a 'narrow piece of land' ('strip') in the 'sky' ('air') where planes can land and take off.
