'aperture-related' is a Modern English compound formed from 'aperture' + 'related', where 'aperture' comes from Latin 'apertūra' meaning 'an opening' and 'related' is from the past participle of 'relate' (via Old French/Latin roots).

'aperture' originates from Latin 'apertūra' (from 'aperīre' meaning 'to open') and entered English via Medieval/Scientific Latin and French influences; 'related' comes from Latin 'relatus' (past participle of 'referre') through Old French 'relater' and Middle English 'relaten'; the compound 'aperture-related' is a transparent Modern English formation created by joining the noun 'aperture' with the adjective-forming participle 'related'.

Individually, 'aperture' initially meant 'an opening' and has retained that core meaning in technical contexts; 'related' originally meant 'brought back' (via 'refer') and evolved to mean 'connected to' — together the compound now specifically denotes 'connected with or concerning an aperture'.
