KNOW HOW WORDS FUNCTION
The class of a word is determined by the function it performs in a sentence.
This round is over (NOUN). This is because it functions as a name.
The boat rounded the Island (VERB). This is because it performs an action.
I love round tables (ADJECTIVE). This is because it describes a noun.
He moves round every morning (ADVERB). This is because it describes a verb.
He works round the clock (PREPOSITION). This is because it shows the relationship between the pronoun “he” and the noun “clock”.
The part of speech of a word is mainly determined by the function it performs in a sentence. So, would you like to use any word as different parts of speech/word classes?
