According to common sense an affective feeling or mood can be adequately described with words. Scientifically, there are serious doubts concerning this claim. There are no semantic categories for qualitative aspects of affective experience. The words, in terms of strict semantic meaning, refer to such external (behavioral, physical) designates as: active, placid, tense, energetic, still, etc. Words are used according to lingual habits, cultural tradition or individual lingual inventiveness to describe different affects of feelings; they function as metaphors or allusions (indirect reference to the object of consideration). The question is: what kind of language properties make it possible to verbally describe true affective states? Words, besides fundamental (denotative) meanings, have additional connotative meanings, which express e.g. abstract qualities or common properties of designates and affective values associated with them. The adjectives which are used to describe feelings or qualitative aspects of inner experience have affective connotations as well. The affective connotation of an adjective is a factor which automatically evokes an emotional response in the subject. Viewed from such a perspective, the adjective is not so much the name of an emotion but rather a factor which evokes the said emotion according to its affective connotation. Particular mood valence is associated with the related affective connotation of particular words. As a result, selected words advance in hierarchy and gain privileged position within the working memory. Consequently, the subject displays a tendency to describe their mood with words.
