Onshore → It is formed from "on" (meaning in a position of contact with) and "shore" (from Old English "sceor", meaning the land along the edge of a sea or lake). The word "onshore" refers to something located on or towards the land from the sea.
Think of being 'in contact with' ('on') the 'land' ('shore') — that's why onshore means something that is on the land.
