What is "base fee"

Base \Base\ (b[=a]s), a. [OE. bass, F. bas, low, fr. LL. bassus thick, fat, short, humble; cf. L. Bassus, a proper name, and W. bas shallow. Cf. Bass a part in music.]

3. Of humble birth; or low degree; lowly; mean. [Archaic] ``A peasant and base swain.''

5. Of little comparative value, as metal inferior to gold and silver, the precious metals.

6. Alloyed with inferior metal; debased; as, base coin; base bullion.

7. Morally low. Hence: Low-minded; unworthy; without dignity of sentiment; ignoble; mean; illiberal; menial; as, a base fellow; base motives; base occupations. ``A cruel act of a base and a cowardish mind.''
   --Robynson (More's Utopia). ``Base ingratitude.''

    Base metal. See under Metal.

    Syn: Dishonorable; worthless; ignoble; low-minded; infamous; sordid; degraded.

    Usage: Base, Vile, Mean. These words, as expressing moral qualities, are here arranged in the order of their strength, the strongest being placed first. Base marks a high degree of moral turpitude; vile and mean denote, in different degrees, the lack of what is valuable or worthy of esteem. What is base excites our abhorrence; what is vile provokes our disgust or indignation; what is mean awakens contempt. Base is opposed to high-minded; vile, to noble; mean, to liberal or generous. Ingratitude is base; sycophancy is vile; undue compliances are mean.

A base fee is an interest in real property that has the potential to last forever, provided a specified contingent event does not take place. For example, a grantee might be given an interest in a piece of land, "as long as the land is not used for any illegal purposes."
