What does sparseness mean?
Sparseness is the noun meaning the condition of being sparse: thinly distributed, infrequent, or limited in detail. It commonly describes vegetation, populations, or objects spread across a wide area, but it can also characterize information that is incomplete, scattered, or insufficient to support a firm conclusion. In the latter sense, the word suggests that the available material is too thin to provide adequate coverage, although it does not necessarily mean that none exists. The term is formal and less common than the simpler adjective sparse or the noun sparsity, which is especially frequent in mathematics and economics. Sparseness can also carry a subtle implication of loss, absence, or lack of fullness, making it useful when discussing landscapes, archives, data, or arguments. Its Latin-derived vocabulary connects it cognately with words such as disperse and dispersion, all of which involve scattering rather than gathering.
nounThe quality of being sparse, especially of being thinly dispersed, insufficiently detailed, or occurring at infrequent intervals.
- The quality of being thinly distributed or sparsely populated.
- The lack of detail, information, or coverage in a text, dataset, or presentation.

Sparseness is normally used as an uncountable noun; the plural is uncommon and is chiefly needed when separate instances or types of sparseness are compared.

Sparseness turns abundance on its head: the less there is, the more carefully each remaining detail may matter.

Where does sparseness come from?
Sparseness was formed in English by adding the suffix -ness to sparse. The adjective sparse comes through Middle English from Latin sparsus, a participle of spargere, meaning “to scatter.” Latin spargere also produced cognates represented in English by words such as disperse, dispersion, and dispersal.
