Also known as decypherment
In philology and linguistics, decipherment is the discovery of the meaning of the symbols found in extinct languages and/or alphabets. Decipherment is possible with respect to languages and scripts. One can also study or try to decipher how spoken languages that no longer exist were once pronounced, or how living languages used to be pronounced in prior eras.
