In the realm of translation, we commonly use the terms 'source' and 'target' language. The 'source' language refers to the original language of a document requiring translation, whereas the 'target' language is the language into which the text will be translated. For instance, if a document is written in English and needs to be translated into French, English serves as the source language, and French becomes the target language. The source language is where the translator derives the meaning, while the target language is where the translator articulates that meaning.
