Translation (/trænzleɪʃən/) is the communication of the meaning of a source-language text by means of an equivalent target language text. There are two main types, written translation and spoken translation, also known as interpreting.
Translation in class is generally disapproved of by modern teaching methodologies but it can be occasionally useful.
