Did you know?

Debilitate, enfeeble, undermine, and sap all share the general sense "to weaken." But while debilitate holds the distinction among these words of coming from the Latin word for "weak"—debilis—it packs a potent punch. Often used of disease or something that strikes like a disease or illness, debilitate might suggest a temporary impairment—but a pervasive one at that. Enfeeble, a very close synonym of debilitate, connotes a pitiable, but often reversible, condition of weakness and helplessness. Undermine and sap suggest a weakening by something working surreptitiously and insidiously.

Synonyms

• devitalize
• enervate
• enfeeble

• soften
• tire
