2.3. A Brief Outline of Functional Styles
The Belles-lettres Style. It is the style of creative literature. It is the richest register of communication. Alongside with its own language means, it makes wide use of elements of other FSs. Its functions are informative, persuasive, and aesthetic. The form of presentation in the Belles-lettres style is meaningful and carries additional information. There are three substyles: emotive prose, poetry and drama.
The Style of Official Documents. The main function is to define the condition, binding two parties in some undertaking to reach an agreement between them. These parties may be: the state and a citizen, or a citizen and a citizen, two or more enterprises (business correspondence or contract); two or more governments (pacts, treaties, etc); a person in authority and a subordinate (orders, regulation instructions), etc.

This style is the most conservative in its structure and vocabulary used. Its forms are strictly regulated lexically and grammatically. The most remarkable features are:

• 
  Absence of emotiveness and subjective modality;
  
• 
  The use of words in their logical meaning;
  
• 
  A set of terms, clichés, set-expressions symbols and abbreviation.
