Translation may be compared to a cable composed of many simultaneous strands of transfer. In translation, there is replacement which involves general hierarchical organization, grammatical constructions and constituents, mapping of deep onto surface structures, classes, ordering, lexicon, phonology, concordance, points of ambiguity, and information loss and gain. A fundamental assumption is that the content of a document is independent of the language in which it is expressed. To transmit the content of a document into another language, the translator must be more concerned with the overall effect of his effort than with correspondence of outward form--if he is not to lose the kernel in preoccupation with the husk.
