‎This paper deals with one problem that needs to be addressed in the emerging field known under the name computing with perceptions‎. ‎It is the problem of describing‎, ‎approximately‎, ‎a given fuzzy set in natural‎ ‎language‎. ‎This problem has lately been referred to as the problem of retranslation‎. ‎An approaches to ‎dealing with the retranslation problem is discussed in the paper‎, ‎that is based on a pre-defined set of ‎linguistic terms and the associated fuzzy sets‎. ‎The retranslation problem is discussed in ‎terms of two criteria validity and informativeness‎.
