The verb menguar refers to the process of becoming smaller, decreasing in quantity, intensity, or size. It can be used in various contexts:

Reduction in size or amount: To diminish, shrink, or dwindle. For example, a river level might decrease during a drought, or a pile of supplies might shrink over time.
Loss of intensity or strength: To wane, decline, or fade. This is often used metaphorically for things like enthusiasm, prestige, or authority.

In the present tense, it undergoes a spelling change: yo menguo, tú menguas, él mengua.

Origin:

The word comes from the Vulgar Latin minuare, which itself derives from the Latin minuere (to make smaller, to lessen), the same root that gave English the word "minute" (as in very small).
