Parliaments and legislative bodies around the world impose certain rules and standards during debates. Tradition has evolved that there are words or phrases that are deemed inappropriate for use in the legislature whilst it is in session. In a Westminster system, this is called unparliamentary language and there are similar rules in other kinds of legislative systems. This includes, but is not limited to, the suggestion of dishonesty or the use of profanity. Most unacceptable is any insinuation that another member is dishonourable. So, for example, in the British House of Commons any direct reference to a member as lying is unacceptable, even if the allegation is substantively true. A conventional alternative, when necessary, is to complain of a "terminological inexactitude".
