'electric-current-related' originates from Modern English as a compound: 'electric' + 'current' + 'related'. 'electric' comes from New Latin 'electricus' (ultimately from Greek 'ēlektron' meaning 'amber'), 'current' comes from Latin 'currere' (to run) via Old French/Middle English, and 'related' comes from Latin 'relatus' (past participle of 'referre') via Old French and Middle English.

'electric' developed from Greek 'ēlektron' → New Latin 'electricus' → Modern English 'electric'. 'current' evolved from Latin 'currere' → Old French forms (e.g. 'corant') → Middle English (e.g. 'curraunt') → Modern English 'current'. 'related' came from Latin 'relatus' → Old French 'relater'/'relaté' → Middle English 'relaten' → Modern English 'related'. These elements were later combined in Modern English to form compound descriptors such as 'electric-current-related'.

Initially, 'electric' was associated with amber (static electricity) and later broadened to mean 'relating to electricity'; 'current' originally meant 'running' and shifted to 'flow' (including electric flow); 'related' originally meant 'brought back/mentioned' (from reference) and shifted to 'connected' or 'having a relation'. Combined, the compound now means 'connected with the flow of electric charge'.
