monty
the full monty the full amount expected, desired, or possible. informal
☞ The origin of this expression is unclear. Among various, though unsubstantiated theories, one cites as the source the phrase the full Montague Burton, apparently meaning 'a complete three-piece suit' (from the name of a tailor of made-to-measure clothing in the early 20th century). Another theory recounts the possibility of a military origin, with the full monty being 'the full cooked English breakfast' insisted upon by the British Second World War army commander Field Marshal Montgomery, whose nickname was 'Monty'.
