bánh đa

Often explained as being derived from bánh (“any sweet, salty, or savory food prepared from flour”) +‎ đa (“banyan”), from the supposed resemblance of the rice paper to a banyan leaf.

This name was the result of a taboo-induced lexical replacement of the preexisting bánh tráng, during Lord Trịnh Tráng's rule of Northern Vietnam (1623–1654), when there was naming taboo of Tráng's name. The original term is now preserved in areas of Central and Southern Vietnam, which were not under the reign of Lord Trịnh Tráng at the time.
