could anyone explain this :)
Cases of free modulation are one of instances not yet fixed and sanctioned by translator, so that the procedure must be carried out a new each time. This, however, is not what qualifies it as optional; when carried out as it should be, the translation result should correspond perfectly to the situation indicated by the SL. To illustrate this point, it can be said that the result of a free modulation should lead to a solution that makes the reader exclaim, “Yes, that’s exactly what you would say”.
Thanks beforehand :)
