Structural words differ from the notional words semantically; their lexical meaning is of a more general character than that of the notional words (e.g.: in, and, even, alas). Moreover they sometimes altogether avoid it if they are isolated from the context (e.g.: article the, conjunction that, interjection oh etc.)

Structural words do not perform any independent syntactic function in the sentence structure but serve either to express various relations between the words in a sentence. (e.g: trees in the garden, Tom and Joe, etc.) or to specify the meaning of the words (e.g.: there is a book on the table; the book on the table is mine, etc.

The following parts of speech are to be treated as structural words : articles, particles (only, solely, exclusively, mainly), prepositions and conjunctions. Articles and prepositions are of individual character of English differentiating it from Uzbek as the functions of these parts of speech in Uzbek are performed by other elements of the language.
