Què va passar

The Latin diphthong AU closed into a single o in Spanish, French, Italian and Catalan; rustic Latin already wavered (CAUDA beside CODA, CLAUDIUS beside CLODIUS). French shows the change came late there: in CAUSAM → chose, the c turned to ch as before an a, so the word still began ca- when French palatalized it. Portuguese stopped halfway at ou, still written though Brazilians mostly say [o]; Romanian kept the diphthong (aur).

Descodificador

Where English, Romanian or a learned word has au, the everyday word in the western sisters usually has o (Portuguese ou): aur → oro, or, ouro; treasure (thesaurus) → tesoro, tesouro.

Excepcions

Learned words keep au: causa, aurora, pausa (es/it/pt/ca), cause, aurore (fr), giving doublets like cosa/causa. Words whose AU had already become o in Vulgar Latin show o or u even in Romanian (ORICLA → ureche, CODA → coadă). French pauvre is pronounced [povʁ]: the au there is a later Latinizing spelling, not a surviving diphthong; Portuguese coisa comes from older cousa.

Mira com passa: AURICULAM
