unfailing

Usage Note

Infalible is one of the adjectives that ends in -e and therefore has the same form for masculine and feminine: el método infalible / la receta infalible. In Catholic theology it carries a precise technical sense (infalibilidad papal — papal infallibility). In everyday speech it is used hyperbolically for something that never fails.

Examples

"Tienen un método infalible para resolver el problema."
