'aorist-related' originates as a compound of 'aorist' and 'related'. 'aorist' originates from Greek, specifically the word 'ἀόριστος' (aoristos), where the prefix 'a-' meant 'not' and the root 'horistos' meant 'defined/limited'; 'related' ultimately comes from Latin 'relatus' (past participle of 'referre') via Old French, where 're-' meant 'back' and 'ferre'/'ferre' meant 'to carry/bring.'

'aorist' changed from Greek 'aoristos' into Latin and French forms (e.g. Latinized aoristus, French aoriste) and eventually became the English word 'aorist'; 'related' developed from Latin 'relatus' through Old French 'relater' into English 'relate' and the adjective 'related', and the compound 'aorist-related' is a modern English formation combining the two.

Initially 'aoristos' meant 'indefinite' or 'not limited' in Greek, and over time 'aorist' came to denote a specific tense/aspect (simple or undefined past) in grammatical terminology; 'related' originally carried the sense 'brought back' / 'referred' but evolved to mean 'connected to', so the compound now means 'connected to the aorist'.
