Parts of speech

Parts of speech

We can distinguish parts of speech into three groups:

1. Notional parts of speech 
2. Free parts of speech
3. Structural parts of speech

Notional parts of speech comprise words denoting things, their qualifies, their actions and states, etc. Nouns, adjectives, pronouns, numerals, verbs and adverbs are notional parts of speech.

Modal words, interjections are free parts of speech. These words do not enter into the structure of the sentences as parts of sentences,

Structural parts of speech have no independent function in the sentences, we use them to connect words and sentences (prepositions and conjunctions) or to specify and emphasize the meaning of words (particles and articles).
