Prefix

A prefix is the initial portion of some linear object (usually text or speech, but one could speak of the prefix of a parade) with a separate meaning, typically modifiying the meaning of the remaining part.

For example, the word prefix is made up of the base fix (meaning "attach" in this case), and the prefix pre-, meaning "before". To prefix is to attach before.

Specific types of prefixes include:

• Prefix (linguistics), a type of affix that precedes the morphemes
• SI prefix, used for magnitudes of SI units, like 'kilo' and 'milli' in 'kilometre' and 'milligram'.
• Polish notation, a method of mathematical expression, also known as prefix notation
• Telephone prefix, the first set of digits in a telephone number not a country code or area code
• ITU prefix, a call sign for radio and television stations
• Prefix (computer science), of a string
• Prefix code
