Etymology

Unknown. Antonym of aprīcus. Long compared with Proto-Germanic *abuhaz (“turned the wrong way, wicked”), Sanskrit अपाञ्च् (ápāñc, “located backwards, behind”), Serbo-Croatian опак, ȍpāk (“wicked, evil”), which are from Proto-Indo-European *h₂epó (“away”) and Proto-Indo-European *h₃ekʷ- (“see”); the Latin would be via metathesis from *apōcus.
De Vaan remains unconvinced and suggests Proto-Italic *op-wākos (“situated towards the empty side”), from Proto-Indo-European *h₁epi (Latin ob) and Proto-Indo-European *h₁weh₂- (“empty”) (Latin vacuus and vānus), with the same phonetic development as in oportet.
