How to say "descriptor" in Japanese

• ディスクリプタ
  nounThe direct loanword, covering the technical sense of 'descriptor'—a term or piece of data that describes something, as in computing; use it where an English text would simply keep the word 'descriptor'.
• 記述子きじゅつし
  nounThe kanji equivalent, built from 記述 'description'; it covers the same technical sense as the loanword—something that describes or characterizes something else—and is understood as the native rendering of the English term.
• 指定子していし
  nounGlossed as both 'descriptor' and 'designator', but built from 指定 'designation', it really denotes something that specifies rather than describes; treat it as 'designator' and look elsewhere for 'descriptor'.

For 'descriptor' in its technical sense—a term or piece of data that describes something—use the loanword 「ディスクリプタ」 or the kanji equivalent 記述子; 指定子 really means 'designator', for something that specifies rather than describes.
