Functional Words Essay

To the basic functional series of words in English belong the article, the preposition, the conjunction, the particle, the modal word, the interjection.
The article expresses the specific limitation of the substantive functions.
The preposition expresses the dependencies and interdependences of substantive referents.
The conjunction expresses connections of phenomena.
The particle unites the functional words of specifying and limiting meaning. To this series, alongside of other specifying words, should be referred verbal postpositions as functional modifiers of verbs, etc.
The modal word, occupying in the sentence a more pronounced or less pronounced detached position, expresses the attitude of the speaker to the reflected situation and its parts. Here belong the functional words of probability (probably, perhaps, etc.), of qualitative evaluation (fortunately, unfortunately, luckily, etc.), and also of affirmation and negation.

A preposition links nouns, pronouns and phrases to other words in a sentence. The word or phrase that the preposition introduces is called the object of the preposition.
A preposition usually indicates the temporal, spatial or logical relationship of its object to the rest of the sentence as in the following examples:
The book is on the table.
The book is beneath the table.
The book is leaning against the table.
The book is beside the table.
She held the book over the table.
She read the book during class.
In each of the preceding sentences, a preposition locates the noun "book" in space or in time.
A prepositional phrase is made up of the preposition, its object and any associated adjectives or adverbs. A prepositional phrase can function as a noun, an adjective, or an adverb. The most common prepositions are "about," "above," "across," "after," "against," "along," "among," "around," "at," "before," "behind," "below,"
