      • 2022 November 18, Ian Sample, “Earth weighs in at six ronnagrams as new prefixes picked for big and small”, in The Guardian‎:

        The chosen prefixes won the vote in part because they start with the only two letters left in the alphabet that are not already used in measurement. The b for “bronto” is already used for bytes and h for “hella” is used for hecto, the prefix for 100.

   2. (telecommunications) A set of digits placed before a telephone number, to indicate where the number is based, what type of phone number it is (landline, mobile, toll-free, premium rate etc.)

      in the UK, a number with an 0800 prefix is a toll-free number.

      Add the prefix +34 to dial a Spanish number from abroad

   3. A title added to a person's name, such as Mr. or Dr.
   4. (computing) An initial segment of a string of characters.

      The string "abra" is both a prefix and a suffix of the string "abracadabra".

使用する際の注意点

• Though much less common, a plural form prefices is seen as well, apparently formed by analogy with index–indices, appendix–appendices, and so on, but it is not a standard plural and has no basis in Latin.
