Nominal (disambiguation)
From Wikipedia, the free encyclopedia
Nominal generally derives from Name but it has specific meanings in the following areas:
- In economics a nominal value indicates the listed value of an item in a monetary currency as opposed to the 'real' value in terms of purchasing power. See real versus nominal value.
- In engineering, nominal signifies the subject being in accordance with engineering specification. An example would be if a screw driver is used for driving screws, then it is implemented nominally. Using a screw driver as a hammer is an off-nominal implementation of a screw driver. Among engineers, the word nominal is often used interchangeably with normal. Their technical meanings are different and to use the terms interchangeably is an equivocation. The nominal diameter of a screw is the diameter of the outside edge of the screw thread.
- In linguistics, a "nominal" is a word or group of words functioning as a noun. The word is also sometimes used as a shortened form of "nominal phrase", a synonym for "noun phrase". "Nominal" can also mean a sequence of one or more nouns that do not form a complete noun phrase.
- In statistics nominal data is a form of categorical data where the order of the categories is not significant. This is sometimes contracted to nominals.
- In law, nominal damages may be assessed by a jury or judge in a lawsuit when it is found that the defendant committed the act complained of by the plaintiff, but that no harm was suffered by the plaintiff as a result.
