Decipherment (in philology) is the discovery of the meaning of texts written in obscure languages, which are almost always ancient. Decipherment in cryptography refers to decryption. The term is used sardonically in everyday language to describe attempts to read poor handwriting. In genetics the term is used to describe successful attempts to understand DNA, which is viewed metaphorically as a text containing word-like units. Throughout science the term decipherment is synonymous with the understanding of biological and chemical phenomena.
