Communication
Communication (from Latin commūnicāre, meaning "to share") is the act of conveying intended meanings from one entity or group to another through the use of mutually understood signs and semiotic rules.
Language
Language is a system that consists of the development, acquisition, maintenance and use of complex systems of communication, particularly the human ability to do so; and a language is any specific example of such a system.
Philology
Philology is the study of language in oral and written historical sources; it is a combination of literary criticism, history, and linguistics. Philology is more commonly defined as the study of literary texts as well as oral and written records, the establishment of their authenticity and their original form, and the determination of their meaning. A person who pursues this kind of study is known as a philologist.
Translation
Translation is the communication of the meaning of a source-language text by means of an equivalent target-language text. The English language draws a terminological distinction (not all languages do) between translating (a written text) and interpreting (oral or sign-language communication between users of different languages); under this distinction, translation can begin only after the appearance of writing within a language community.
Language
Evolution teaches us the original purpose of language was to ritualize men's threats and curses, his spells to compel the gods; communication came later.

How else can I say it? I don't speak no other languages.

Translation
You've often heard me say – perhaps too often – that poetry is what is lost in translation. It is also what is lost in interpretation. That little poem means just what it says and it says what it means, nothing less but nothing more.
Robert Frost, A Backward Look, by Louis Untermeyer (1964), p. 18.
