Spanish

Etymology

According to the RAE, borrowed from Portuguese ostra, ultimately from Latin ostrea. But Mackenzie seems to treat this Spanish word as a straightforward inheritance from the Latin word, with the non-breaking of o due to metaphony triggered by the -e-, which became a subsequently-lost glide.
