From Vulgar Latin *plattus (“flattened”), from Ancient Greek πλατύς (platús). As the Spanish word was attested rather late in time, such as in Cervantes' Don Quixote of 1605, there are theories that it may have been a borrowing from Portuguese (where the phonetic shift of the Latin consonant cluster -pl- to -ch- is more normal; in Spanish, it usually becomes -ll-), or alternatively that it may have been a popular word used by the people that did not make its way into written documents prior to Spanish Golden Age literature, as it was only learned people and scholars writing in the Middle Ages. The phonetic evolution in this case may be explained by the word often having been postconsonantal (such as es chato, los chatos, un chato, etc.), which would fit in more with Spanish phonetic norms (compare henchir, hinchar). Doublet of plato, which in contrast to chato has a more learned quality. Cognate to Portuguese chato, Catalan plat, French plat, Italian piatto.
