Synonyms & Antonyms

Root Explanation

Unirradiated → It is formed from "un-" (meaning not) and "irradiated" (from Latin "irradiatus", meaning to shine upon or to emit rays). The word "unirradiated" means not having been exposed to radiation or light.

Memory Tip

Think of 'not' ('un-') having been 'shone upon' ('irradiated') — that's why unirradiated means something that hasn't been exposed to light or radiation.
