frugality n.

1530s, "economy, thriftiness," from French frugalité (14c.), from Latin frugalitatem (nominative frugalitas) "thriftiness, temperance, frugality," from frugalis (see frugal).

FRUGALITY. The disposition to save or spare what we have got, without any desire to gain more. It is constantly, of course, associated with avarice ; but quite as frequently with generosity, and is often merely an extreme degree of housewifely habit. [Ruskin, "Fors Clavigera"]
