What is the difference of "wreck" and "ruin"?
To "ruin" something means to cause damage to it or cause it to stop working. To "wreck" is a little bit more extreme than to "ruin", and means to completely destroy something in a severely violent way. Ex: The cancelation ruined my plans. Ex: The crash wrecked my car. In these examples, you can see that "wreck" is more violent and physically damaging than "ruin". To "wreck" in this case means that there was a lot of physical damage done, while "ruin" here just refers to the plans not working out.
