Particles

Particles are functional words of specifying and limiting meaning. They show subjective attitude. They refer to the word (or phrase) immediately following and give special prominence to the notion expressed by this word, or single it out in some other way, depending on the meaning of the particle. One just does what is reasonable. She could feel anger, even at this late date.

It can stand apart from the word it refers to – I have only met him twice. It is a specific part of the sentence, because without it the meaning of it changes.

The particle not deserves special treatment. It may stand outside the predicate – Not till we landed did we realize that we are alive. Or in short answers: Certainly not. Perhaps not. Of course not. (with modal words). It appears to be the main part of the sentence. Another use is within the predicate, as part of the verb: I am not, he is not, she does not. Here the particle is an auxiliary element within the morphology of the verb, and it has no syntactic function of its own. Its becoming a morpheme within the verb form is seen in the contracted forms isn’t, wouldn’t.

Sometimes the word almost causes doubts whether it is an adverb or a particle: The boat almost overturned. – whether it shows the subjective attitude (it was in danger of overturning) or it denotes the manner in which the action was conducted. It can be felt in the translation – чуть не перевернулась – particle, почти перевернулась – adverb.
