fob

Once upon a time, people carried pocket watches in a tiny pocket called a fob pocket, and the short chain or ornament attached to the watch also came to be called a fob. Later, the word moved into the phrase fob off. If someone fobs you off, they try to get rid of you with a weak excuse, a quick answer, or something less good than what you wanted. Imagine asking for real help and getting a polite but useless reply instead. Today, many people know the word from a key fob: the small device on your keychain that unlocks a car or opens a secure door.

The word "fob" has a layered history that moves from clothing to social behavior to modern gadgets. In early use, it referred to a small pocket, especially the little pocket in breeches or a vest made for carrying a pocket watch. From there, the word was also used for the short chain, ribbon, seal, or ornament attached to the watch. So in older English, a fob could mean either the small pocket itself or the decorative attachment hanging from the watch.

The verb use appears in the phrasal verb "fob off." To fob someone off is to put them off with an excuse, a false reason, or a poor substitute instead of dealing with the matter properly. You can fob a person off with a vague promise, or fob off an inferior product as if it were acceptable. If you complain about a serious problem and receive a shallow, scripted answer meant only to end the conversation, you are being fobbed off. The idea is avoidance: someone is trying to satisfy you just enough to make you go away.

In modern life, the most common noun use is probably in key fob. This means a small device, usually carried on a keychain, that unlocks a car, starts an engine remotely, or gives access to a building. That modern sense does not come from the verb meaning "to put someone off"; it continues the older noun idea of a small attached object. Whether it refers to a watch accessory from the past, a device in your pocket today, or the act of brushing someone aside with excuses, "fob" is a compact word with several distinct but well-established uses in English.
