Ashore means on the land at the edge of a sea, a lake, or a river — or moving towards that land. You come ashore when you leave a boat and step onto the beach, the rocks, or the dock. Sailors contrast life ashore (on land) with life at sea. It is an ordinary word, more at home in ship stories and swimming than in city talk. Though actually it is about reaching land, not only about sand: “we went ashore in the town” can mean you left the ship and walked into streets. Onshore is a cousin, but it often describes wind, oil, or business on land, while ashore is where a person or a boat ends up.
