    Welcome to SE! Thank you for including a sample sentence. What research have you done? What words have you tried and rejected? – miltonaut Dec 1 '18 at 18:29
  • You can try using a synonym such as "mutiny", "revolt", "rebel", but there's probably nothing that carries the precise same legal implications. – Hot Licks Dec 1 '18 at 18:35

    Any normal person would simply use the noun treason in your context (committing is completely redundant). If you're determined to use an alternative, and you don't mind sounding pretentious, consider treasonry (obsolete, rare, according to the full OED). – FumbleFingers Dec 1 '18 at 18:36

Treason is a defined legal concept, so has a definite meaning. There's no verb form of treason. Use

The corporal was on trial for treason.

    "Defined legal concept" doesn't entail "there's no verb form," unless you can explain why. – Azor Ahai Dec 1 '18 at 20:44
  • @AzorAhai I don't think he was making an implication, just stating independent facts. – Barmar Dec 4 '18 at 8:05

The verb is the same as the noun - 'treason'. But the verb form is stated by the OED to be 'rare'.

13.. K. Alis. 723 Thy fadir hastow tresond here! c1330 R. Mannyng Chron. (1810) 105 Þei wer fulle wele knowen, þat wild haf tresond him. c1374 Chaucer Troilus & Criseyde iv. 410 (438) To traysen [v.r. trassen] a wight þat trewe is vn-to me. 1890 L. Lewis Proving of Gennad xv. 104 Ere morning, thou shalt know who treasons thee. (Hide quotations)


No verb springs to mind, but the sentiment is captured by treachery.

treachery noun

1 : violation of allegiance or of faith and confidence : treason

2 : an act of perfidy or treason

  • Marriam-Webster

So the sentence would read: "The corporal was on trial for treachery".

Note: As others have pointed out, certain words have different and specific meanings in law, so it depends whether you are describing the actual crime they are being tried for, or simply a general statement about its nature.

  • Treachery describes behavior or character. Treason is a criminal offense. No one is on trial for treachery. – michael.hor257k Dec 1 '18 at 21:32
  • It is quite literally an act of treason. Much as one could be on trial for blowing up a house, and charged with arson, one may on trial for treachery and charged with treason. – Freddie R Dec 1 '18 at 21:34
  • I don't think anyone would say "The corporal was on trial for killing." – michael.hor257k Dec 1 '18 at 21:42
  • One could say "The corporal was on trial for killing his commanding officer", but since "treachery" doesn't really have the same construction so it is fine to leave as is. – Freddie R Dec 1 '18 at 22:06

    But OP asks for a verb, while treachery is a noun. If OP wanted to use a noun they could just use treason. – The Photon Dec 2 '18 at 1:29
