Realia (translation)
In translation, Realia  (plural noun) are words and expressions for culture-specific material elements. The word realia comes from medieval Latin, in which it originally meant "the real things", i.e. material things, as opposed to abstract ones. The Bulgarian translators Vlahov and Florin, who were the first to carry out an in-depth study of realia, coined the modern sense of the word. They indicate that since realia carry a very local overtone, they often pose a challenge for translation.
