Antonyms

Treated with a small amount of another substance to change how it behaves

Surface Forms

undoped positive

Morphology

undoped = doped (transparent) = un + dope + ed

Formed by negating 'doped' (treated with dopants) using the productive prefix 'un-'; meaning is compositionally clear.

Etymology

Undoped is made of un- 'not' and dope 'to add a substance to change something'. In science 'to dope' means to add a small amount of another element to change how a material behaves, so undoped means 'not treated with such an additive'.
