In language, 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 (which does not exist in all languages) between translating written texts and interpreting oral or signed communications between languages. A translator always risks inadvertently introducing source-language words, grammar, or syntax into the target-language rendering. Such "spill-overs", however, have sometimes imported useful source-language calques and loanwords that have enriched target languages. Since the 1940s, efforts have been made, with varying degrees of success, to automate translation or to mechanically aid the human translator. More recently, the rise of the Internet has fostered a world-wide market for translation services and has facilitated "language localisation".
Etymology
The word for the concept of "translation", in English and some other European languages, stems from the Latin noun translatio, formed from the adverb trans, "across", and -latio, derived from latus, the past participle of the verb ferre, to "carry" or "bring". Thus, the Latin noun translatio and its cognate modern derivatives mean the "bringing across" (i.e., the transferring) of a text from one language to another. In some other European languages, the word for the concept of "translation" stems from another Latin noun, trāductiō, derived from the verb trādūcō, "bring across", formed from the adverb trans, "across", and dūcō, to "lead" or "bring". The Ancient Greek term for "translation" (metaphrasis, "a speaking across") has supplied English with "metaphrase" (word-for-word translation), as contrasted with "paraphrase" (rephrasing in other words, from paraphrasis). "Metaphrase" corresponds in one of the more recent terminologies to formal equivalence, and "paraphrase" to dynamic equivalence. The concept of metaphrase (i.e., word-for-word translation) is imperfect, because a given word in a given language often carries more than one meaning, and because a similar given meaning may often be represented in a given language by more than one word. Nevertheless, metaphrase and paraphrase may be useful as ideal concepts that mark the extremes in the spectrum of possible approaches to translation. See also the entry for translation at Wiktionary.
Theories
Western theory Discussions of the theory and practice of translation reach back into antiquity and show remarkable continuities. The ancient Greeks distinguished between metaphrase (literal translation) and paraphrase. This distinction was adopted by English poet and translator John Dryden (1631–1700), who described translation as the judicious blending of these two modes of phrasing when selecting, in the target language, "counterparts", or equivalents, for the expressions used in the source language:
