Final answer:

Step-by-step explanation:
In English grammar, when referring to syntax, there are four major parts of speech: nouns, adjectives, verbs, and adverbs. These four parts of speech constitute over 95% of all words in the English language.
Nouns are words that represent people, places, things, or ideas. For example, 'dog', 'book', and 'love' are all nouns.
Adjectives are words that describe or modify nouns. They provide more information about the characteristics of a noun. For example, in the phrase 'blue sky', 'blue' is an adjective describing the noun 'sky'.
Verbs are words that express action, occurrence, or state of being. They are often the main word in a sentence. For example, 'run', 'sing', and 'is' are all verbs.
Adverbs, on the other hand, modify verbs, adjectives, or other adverbs. They provide more information about how, when, where, or to what extent an action or quality is happening. For example, in the phrase 'she sings beautifully', 'beautifully' is an adverb modifying the verb 'sings'.
