Usage
What does ruin mean? Ruin is most commonly used as a verb meaning to destroy or spoil. As a noun, ruin means the remains of a destroyed or decayed place, especially a half-standing building or city. It is most commonly used in the plural, as in ancient ruins. Example: I feel like the once-quiet atmosphere of the ancient ruins has been ruined by the presence of too many tourists and commercial vendors.
Related Words
Ruin, destruction, havoc imply irrevocable and often widespread damage. Destruction may be on a large or small scale ( destruction of tissue, of enemy vessels ); it emphasizes particularly the act of destroying, while ruin and havoc emphasize the resultant state. Ruin, from the verb meaning to fall to pieces, suggests a state of decay or disintegration (or an object in that state) that is apt to be more the result of the natural processes of time and change than of sudden violent activity from without: The house has fallen to ruins. Only in its figurative application is it apt to suggest the result of destruction from without: the ruin of her hopes. Havoc, originally a cry that served as the signal for pillaging, has changed its reference from that of spoliation to devastation, being used particularly of the destruction following in the wake of natural calamities: the havoc wrought by flood and pestilence. Today it is used figuratively to refer to the destruction of hopes and plans: This sudden turn of events played havoc with her carefully laid designs. See spoil.

Explanation
To ruin means to wreck or destroy. If you're wearing a long dress, make sure your clumsy brother stays away from you. If he steps on it, it'll rip and be ruined. Bad news always ruins your day and a guest's bad behavior can really ruin a party and all your fun! Be careful when adding salt to your food — too much will ruin it. Often you will see ruin used as a noun that means the state of ruin, the action that causes it or the destruction itself. If you are a ruin of your former self, you're in pretty bad shape. Use ruins for the remains of old castles and Roman structures.
