Means of expressing modality in Modern English

For example: Our Success really (particle) small.
I listened: really (modal Word), it was the voice.
On the value modal words can be divided into two groups: 1. Modal words with positive value, expressing the logical evaluation of the speech, the speaker's belief in the reality of the absolute authenticity of messages: definitely, true, really, of course, no doubt, of course, etc.
For Example: Two by two, of course, four.
One day, undoubtedly, this Lake will dry up.
To this group belong the phraseological combinations: in fact, it goes without saying, etc.
2. Modal words with the alleged value of expressing possibility, problematical validity (assumption, the probability of admission, doubt): likely, possible, likely, it seems, probably, etc.
For Example: It seemed to me that he probably looked a long time at the door before you enter Eighty-year-old poetess, perhaps, came to this thought through experience gained in the course of her life. A sense of melancholy, probably, is inherent in every. This includes a combination of "maybe", "should", "probably" etc. Modal words differ from significant, to whom they are related by descent, the absence of nominative function. Modal words are not the names of objects, signs or processes, identified significant words; they have no words, grammatical constituent sentence and are not members of the sentences. Once an isolated in the sentence, the words are the modal lexicalization. Lose not only the variability, but morphological dividedness. So, the combination of "maybe" by getting the value of modal words, often loses the second word (be), and the inflection-em in the word "may" lose the inherent value. It is known that in English, the words express the relationship of the author modal to your statement, indicating confidence, doubt, suggested a positive or negative assessment of what is said in the sentence. Modal words can be simple (sure, perhaps), derivative (surely, naturally, really) and composite (maybe, to be sure). [6,98]
The most common modal words include:

• 
  the modal words expressing doubt and the assumption, uncertainty in reliability of the reported: maybe, perhaps, probably;
  
• 
  the modal words expressing approval or disapproval: fortunately, unfortunately, luckily, unluckily, happily, unhappily;
  
• 
  the modal words expressing strengthening: really;
  
• 
  the modal words expressing confidence, reliability of the reported: course, sure, surely, to be sure, sure enough, evidently, obviously, no doubt, naturally, really.
  

Let's review the examples:

1. 
   Perhaps, you’re right. – Возможно, вы правы.
   
2. 
   Unfortunately, the weather was bad. – К сожалению, погода была плохая.
   
3. 
   I really don’t know what’s to be done. – Я действительно не знаю, что предстоит сделать.
   
4. 
   Maybe Mary is ill. – Может быть, Мери заболела.
   
5. 
   No doubt he will come later. – Он, без сомнения, придет позже.
   
6. 
   Of course I understand it. – Конечно, я понимаю это. Characteristics of modal words of the syntax are as follows:
   

1) the use in value of the word-sentence, more often in the dialogical speech: Can I borrow your pen? – Of course. - Можно я одолжу у вас ручку? –Конечно. 2) the use as a parenthesis: You to me, of course, do not have any business 3) the use as affirmative words in the value close to modal particles and adverbs; Certainly, the poet is talented ("certainly" approaches with a modal particle yes). - The poet is certainly talented (certainly - an attributive adverb). – The poet is certainly talented (certainly - the modal word as introduction). As said above, modal words in sentence function induction of members. But note that if all the modal Word can serve as an introductory Word, not every introduction is modal. According to it a modal does not include: [6,92]

• 
  introductory words, expressing the emotional evaluation of messages (Fortunately, unfortunately, to surprise, to the chagrin of);
  
• 
  introductory words expressing someone's speech (say, rumored to be);
  
• 
  introductory words, indicating the sequence of thoughts (first, last, therefore, so, etc.).
  

As we have already pointed out, the category of modal words usually include indicators expressing a high level of confidence, some researchers called their performance "a categorical reliability " (undoubtedly, certainly, undoubtedly, for certain, by all means, of course, certainly, naturally, really, etc.), The indicators of uncertainty entering assumptions (probably, truly, probably it seems, obviously, probably, apparently, it is visible, apparently, most likely, apparently, perhaps, it seems as if, seemingly, most likely, it has to be, maybe, possible, hardly, in my opinion, and so forth.). Among the words entering value of the assumption, doubt indicators sometimes are separately considered (unlikely, hardly Some authors instead of category of the assumption enter category of opportunity (can be, probably, it is probable and so forth).
In conclusion of this point follows, that modal means in speech realization play very essential role.
In researches of a number of linguists, psycholinguists, psychologists the aspiration to present modal means in the classified look is observed: in the generalized schemes, tables, classifications; they are considered generally as the introduction element, the isolated particles, words and phrases.
Syntactic Functions of Modal Words
Features of their syntactic functions belong to syntactic features of modal words and their compatibility within other words.
Carrying out function of an introduction sentence part, modal words most often belong to all sentences, but can treat one of his members. When the introduction sentence part expressed by the modal word, belongs to all offer, it can stand at the beginning, in the middle or, rarer, at the end of the sentences. The place of the introduction member expressed by the modal word, in the sentence is reflected in degree of its coherence with contents of the sentence and at a brightness of expression of a modal shade.
Probably, they were right to keep him.
They were probably right to keep him.
They were right to keep him, probably.
These examples show, in – the first that the modal word is most closely connected with contents of the statement between sentence parts, and, on the contrary, less all is connected with it at statement at the end of the sentence, and, in – the second that the shade transferred by the modal word, is expressed most brightly at the use of such an introduction member at the beginning of the sentence. [7,124]
The modal word usually belongs either to a loose part of the sentence or to the second homogeneous part of the sentence (including a predicate): Some lingering irritability appeared to find a resting place in Mr. Winkle`s bosom, occasioned possibly by the temporary abstraction of his coat. (Ч. Диккенс) It is interesting to note that modal words with value of the assumption (perhaps, maybe, possibly) most often belong only to one of sentence parts. [7,132]
Compatibility of modal words is very limited. Modal words can have the definition expressed by a degree adverb: most probably
