Not dense; widely scattered
Having only a few things in a big space, so they are not close together.
用法パターン：
sparse [noun]
よくある間違い：
Learners sometimes use 'sparse' when they only mean 'small'. 'Sparse' usually means that there are not many things and they are spread out over space. For example, a 'small room' is not 'sparse', but a 'sparse forest' has few trees that are far apart.
類義語
thin (Suggests something that is not thick or full, often used for hair, crowds, or vegetation; slightly more general than 'sparse'.)
|

対義語

Small in amount or number
Very little in amount or number; not enough of something.
用法パターン：
sparse [noun]
よくある間違い：
Learners sometimes confuse 'sparse' with 'rare'. 'Sparse' usually describes quantity (there is not much of something) or distribution, while 'rare' often describes how often something happens. For example, 'sparse information' is correct, but we usually say 'rare events', not 'sparse events'.
類義語
scarce (Focuses more on not having enough of something, especially something needed or wanted.)
|
meager (Suggests an amount that is very small and often disappointing or poor in quality.)
対義語
plentiful (Describes something that exists in large quantities, the opposite of a small or insufficient amount.)
|
abundant (Emphasizes having more than enough of something.)
