ENWhile communicating language reveals relations between the speakers, the social context is also highlighted. Language etiquette is the expression of linguistic politeness. The Lithuanian language has nouns which denote a person but have no meaning of gender. These are nouns of more common meaning, they are used to name both a male and female person (e. g.: akìplėša, válkata, marmalas). According to the form some of them are of masculine gender (e. g., marmalas), others are of feminine gender (e.g., valkata), however, in some contexts they are masculine, in other feminine, e.g.: jis akiplėša / ji akiplėša. The pronoun shows what person (i.e. of what gender) this evaluation belongs to. Substantiva communia most often are words of the spoken language, dialectal words. The most important feature of SC is that they express subjective (most often negative) characteristic of a person (creature). These nouns highlight the feature, the speaker expresses emotionly his / her evaluation and attitude.Most of SC have derogatory, contemptous meanings ñ they are pejoratives.
