transpose, the syntactic structures of the source text into correct structures in the target text. will find a variety of reasons have to change structures into something quite different further down the line to achieve target language naturalness.
Working on the text level, you intuitively and automatically make certain 'conversions1; you transpose the SL grammar (clauses and groups) into their 'ready1 TL equivalents and you translate the lexical units into the sense that appears immediately appropriate in the context of the sentence.
Your base level when you translate is the text. This is the level of the literal translation of the source language into the target language, the level of the trans-lationese you have to eliminate, but it also acts as a corrective of paraphrase and the parer-down of synonyms. So a part of your mind may be on the text level whilst another is elsewhere. Translation is pre-eminently the occupation in which you have to be thinking of several things at the same time.
