Parsimonious
PARSIMO'NIOUS, adjective [See Parsimony.] Sparing in the use or expenditure of money; covetous; near; close. It differs from frugal, in implying more closeness or narrowness of mind, or an attachment to property somewhat excessive, or a disposition to spend less money that is necessary or honorable.
Extraordinary funds for one campaign may spare us the expense of many years; whereas a long parsimonious war will drain us of more men and money.
[It is sometimes used in a good sense for frugal.]
