Middle English: from Irish or Scottish Gaelic bogach, from bog 'soft'.

  • In Gaelic bog means ‘soft’, and this is the source of our word. In the slang sense ‘toilet’, bog was originally bog-house, which is recorded as early as 1665. The British Labour Party spin doctor Alistair Campbell caused widespread offence in 2001 when he said that ‘The day of the bog-standard comprehensive school is over’. Bog standard is first recorded in print as recently as the mid 1960s, although people working in the British motor industry remember it being used a little before this. It may be a reference to bog in the sense ‘lavatory’, but it is more likely to be an alteration of box standard, meaning either ‘made in a standard form and packaged in a box’ or ‘shaped like a box, plainly designed, and without refinements’.
