🇬🇧
/nɒnˈreɪdɪeɪtɪŋ/
not giving off rays or emission
Etymology
'nonradiating' is formed from the prefix 'non-' (meaning 'not') + the present participle 'radiating' of 'radiate', where 'radiate' ultimately comes from Latin 'radiāre' and the root 'radius' meant 'ray'.
'radiate' changed from Latin 'radiāre' and Late Latin 'radiātus' into Middle English forms and eventually became modern English 'radiate'; the negative prefix 'non-' was attached in English to create compounds such as 'nonradiating'.
Initially, 'radiate' meant 'to emit rays'; over time it broadened to 'emit energy, heat, or light' in general, and 'nonradiating' developed to denote the absence of such emission.
