A-bŭn'dant, a.

a. [Lat. abundans, p. pr. of abundare; Fr. abondant. See ABOUND.] Fully sufficient; plentiful.

Thy abundant goodness shall excuse This deadly blot in thy digressing son. Shak.

Synonyms— Ample; plentiful; copious; plenteous; exuberant; overflowing; rich. See AMPLE.

Abundant number (Math.), one, the sum of whose aliquot parts exceeds the number itself. Thus, 1, 2, 3, 4, 6, the aliquot parts of 12, make the number of 16. This is opposed to a deficient number, as 14, whose aliquot parts are 1, 2, 7, the sum of which is 10; and to a perfect number, which is equal to the sum of its aliquot parts, as 6, whose aliquot parts are 1, 2, 3.
