The article is dedicated to some grammar items functions in spontaneous speech when they lose their semantics and acquire some pragmatic meaning. The research is based on the corpora material, the Corpus of Spoken Russian Language, module «One Speaker's Day» (the ORD corpus). Some new functions are demonstrated in the article, such as courtesy forms zdras'te, pozhalsta, izvini(te), parenthetic word skazhem, adverb tam, particle vot, collocations kak jego (jejo, ix, eto). The main object is the multyfunctional character of such items and its long evolution. No doubt such features should be described in specific dictionaries and included into books for Rus-sian and foreign students.
