'exactness-oriented' originates from modern English, specifically by combining the noun 'exactness' and the adjectival suffix '-oriented', where 'exactness' denotes 'the state of being exact' and '-oriented' indicates 'directed toward'.

'exactness' derives from the adjective 'exact', which ultimately comes from Latin 'exactus' (the past participle of 'exigere'); the suffix '-oriented' is built on 'orient' (from Latin 'orient-', from 'oriri' meaning 'to rise'). These elements were joined in modern English to create compound descriptors of the form 'X-oriented'.

Initially, Latin 'exigere' and its form 'exactus' carried senses of 'drive out/measure/require', which shifted toward precision and strictness in later usage; consequently the modern compound evolved to mean 'directed toward precision or exactness'.
