The crime of getting someone else to commit a crime for you, especially of getting a witness to lie in court. It is the noun of *suborn*, and in practice it almost never appears alone — the standard legal term is *subornation of perjury*, which is a separate offence from perjury itself. That distinction is the useful thing to learn. If you lie under oath, that is perjury. If you persuade, bribe, or threaten someone else into lying under oath, that is subornation of perjury, and in many places it is punished at least as heavily, because the law treats organising a lie as worse than telling one. The word is uncountable and extremely formal: indictments, law textbooks, courtroom scenes. Outside law it occasionally means the general corrupting of someone into wrongdoing (the subornation of a public official), but even that keeps a legal flavour. In ordinary English, people just say 'witness tampering' or 'he paid them to lie'.
