The words "fake" and "counterfeit" are often used interchangeably, but there are subtle differences. "Fake" is a more general term, meaning something is not genuine or real. "Counterfeit," on the other hand, specifically refers to an imitation of something valuable, intended to deceive. Think of it this way: a fake watch might just be a cheap imitation, while a counterfeit watch is a deliberate copy designed to look exactly like a luxury brand, intending to trick people into thinking it's the real thing.

Here are some example sentences to illustrate the difference:

• Fake: He wore a fake beard to the party. (He wore a beard that wasn't real.)
• Fake: That diamond is fake. (That diamond isn't a real diamond.)
• Counterfeit: The police seized a large amount of counterfeit money. (The police seized money that was illegally copied.)
• Counterfeit: She was arrested for selling counterfeit handbags. (She was arrested for selling handbags that were illegal copies of real brand name handbags.)

Notice that "counterfeit" almost always implies an intention to defraud. Something that's fake might be made carelessly, whereas something counterfeit is meticulously created to deceive. While all counterfeit items are fake, not all fake items are counterfeit. A child's toy might be described as fake because it's poorly made, but a fake $100 bill is counterfeit because its purpose is to deceive.
