<aside> 💡 When learning basic, intermediate, and advanced structures, it’s best to learn each in context instead of in a linear fashion starting with basic structures, then intermediate structures, and finally the advanced structures. Learning grammar in context often means learning something about each structure as seen within another structure. For example, understanding the part of speech of a word within a prepositional phrase, to see how the prepositional phrase is functioning within a particular clause, to see how the clause functions at the sentence level, etc.

Grammar is the study and system of rules and principles governing the structure and use of language, including the formation of words, sentences, and their components, encompassing syntax, inflections, word formation, and sometimes pronunciation, meaning, and linguistic history. It also involves normative rules for standard usage and may be documented in books for pedagogical or reference purposes, extending to basic principles applicable in various fields of knowledge.
Each word belongs to a particular Parts of speech. Understanding what each word is doing or what it represents will help understand what a phrase (intermediate structures) and clause (advanced structures) are doing or what they represent. Common sentence structures in English are also important to understand at this level.
A group of words that does not contain a subject and a verb is referrred to as a phrase (See Types of Phrases). A phrase is considered an intermediate structure.
A group of words that contain a subject and a verb are called clauses. A clause is considered an advanced structure. See also Types of clauses.
Understanding how a sentence functions within a paragraph relates to written and spoken discourse. Discourse also applies to how a paragraph is functioning within a section, how a subsection is functioning within a section, etc.
