, the 
sentence is the central syntactic construction used as 
the minimal communicative unit that has its primary 
predication, actualizes a definite structural scheme 
and possesses definite intonation characteristics. This 
definition works only in case we do not take into 
account the difference between the sentence and the 
utterance. The distinction between the sentence and 
the utterance is of fundamental importance because 
the sentence is an abstract theoretical entity defined 
within the theory of grammar while the utterance is the actual use of the sentence. 
In other words, a sentence is a unit of language while the utterance is a unit of 
speech. 
The most essential features of the sentence as a linguistic unit are a) 
its structural characteristics – subject-predicate relations (primary predication), and 
b) its semantic characteristics – it refers to some fact in the objective reality.

Thus, by sentence, we understand the smallest communicative unit, 
consisting of one ormore syntactically connected words that have primary 
predication and that have a certain intonationpattern. 
There are many approaches to classify sentences. Below we shall consider 
only some ofthem.
 
B. Ilyish classifies sentences applying two principles: 
1) Types of communication. Applying this principle he distinguishes 3 types 
of sentences: 
declarative, interrogative, imperative
. 
2) According to thestructure. Applying this principle he distinguishes two 
main types ofsentences: 
simple and composite
. 
Ch. Fries
gives an original classification of types of sentences. All the 
utterances are divided by him into 
Communicative
and
