How to say "convict" in Japanese

• 囚人しゅうじんCommon
  nounThe common, general word for a person held in prison; it covers 'convict' in the everyday sense of someone serving a sentence. The default choice in narrative, news, and conversation.
  １０人にんの囚人しゅうじんたちが脱獄だつごくした。↗

  Ten prisoners broke out of jail.
• 既決囚きけつしゅう
  nounCovers 'convict' as 'convicted prisoner': someone whose sentence has been decided by a court. The emphasis is on the conviction being settled; found chiefly in legal writing, and less common than 囚人.
• 服役囚ふくえきしゅう
  nounCovers 'convict' as a prisoner serving a sentence; the nuance is the serving of the term itself. Less common than 囚人, and used when that nuance matters, as in statistics or news about prisons.
  その服役囚ふくえきしゅうは２ヶ月かげつ間かん刑務所けいむしょにいた。↗

  The prisoner was behind bars for two months.
• 受刑者じゅけいしゃ
  nounA person undergoing a prison sentence; used in legal and administrative writing and in news reports. Covers 'convict' as someone serving a sentence.
• 囚徒しゅうと
  nounMeans the same as 囚人 — 'prisoner; convict' — but is less common and seldom the word you want; in your own speech and writing, 囚人 is the safer choice.

All five translate the noun 'convict' — a person in prison — not the verb: 囚人 is the common general word; 既決囚 stresses a conviction finalized in court; 服役囚 and 受刑者 stress serving a sentence; 囚徒 is a less common synonym.
