PRODUCTIVE AFFIXAL MINIMUM OF THE GERMAN LANGUGE ON PSYCHOLOGY FOR DOCTORATE STUDENTS
An idea to compile the affixal minimum was implemented in order to rationally teach doctorate students to translate special texts on psychology in the German language. A Dictionary on psychology [10] containing 3.5 thousand words has been analyzed, the productivity (P) of each affix having been counted as well as mean value (X*) and X**=X* / 2,71 (base of natural logarithm). All the affixes has been ranked according to decrease of their P and the list obtained was divided into three groups. The 1st group was comprised of affixes whose P were more than X*; the 2<sup>nd</sup> group contained affixes characterized by inequality: X* > P > X**: the 3<sup>rd</sup> group contained all the remaining morphemes. This gradated in productivity list of affixes helps students to enlarge their vocabulary.
