Double

Am"ple\, a. [F. ample, L. amplus, prob. for ambiplus full on both sides, the last syllable akin to L. plenus full. See Full, and cf. Double.] Large; great in size, extent, capacity, or bulk; spacious; roomy; widely extended.

2. Fully sufficient; abundant; liberal; copious; as, an ample fortune; ample justice.

Syn: Full; spacious; extensive; wide; capacious; abundant; plentiful; plenteous; copious; bountiful; rich; liberal; munificent.

Usage: Ample, Copious, Abundant, Plenteous. These words agree in representing a thing as large, but under different relations, according to the image which is used. Ample implies largeness, producing a sufficiency or fullness of supply for every want; as, ample stores or resources, ample provision. Copious carries with it the idea of flow, or of collection at a single point; as, a copious supply of materials. "Copious matter of my song." --Milton. Abundant and plenteous refer to largeness of quantity; as, abundant stores; plenteous harvests.
