experimental

adjective eks-peh-ree-men-TAHL Rare

Usage Note

Experimental is a learned adjective borrowed directly from Latin/English and carries the same register — formal and scientific. It does not shorten or change form in front of a noun. In informal speech, Spaniards may use de prueba instead, making experimental feel slightly technical or academic.

Examples

"El tratamiento es todavía experimental."

Natural Translation
