- rătund (regional, dated)
From Latin rotundus (“round”), possibly through a Vulgar Latin form retundus, especially in the case of the variant form, rătund, which was the original form (compare Spanish and Portuguese redondo, archaic Italian ritondo (standard rotondo), Occitan redond, Catalan redó (variant of standard rodó), French rond (Old French reont)). The current standard form of the word may simply be a natural evolution from the older form in southern Romania.
