Nouns can be common (e.g. dog, city), proper (e.g. John, London), collective (e.g. family, team), or abstract (e.g. happiness, freedom).
Verbs can be action verbs (e.g. run, jump), linking verbs (e.g. be, seem), helping verbs (e.g. will, would), and can be transitive or intransitive.
Adjectives can be quantitative (e.g. three, five), qualitative (e.g. big, happy), or demonstrative (e.g. this, that).
Adverbs can be manner adverbs (e.g. quickly, loudly), time adverbs (e.g. yesterday, soon), place adverbs (e.g. here, there), or frequency adverbs (e.g. often, rarely).
Pronouns can be personal (e.g. I, you, he), possessive (e.g. mine, yours), reflexive (e.g. myself, herself), or demonstrative (e.g. this, that).
Prepositions can show location (e.g. in, on, at), direction (e.g. to, from, up), or time (e.g. at, by, during).
Conjunctions can be coordinating (e.g. and, but, or) or subordinating (e.g. because, although, if).

Independent clauses contain a subject and a predicate and can stand alone as a complete sentence.
Dependent clauses contain a subject and a predicate but cannot stand alone and are introduced by a subordinating conjunction.
There are four types of sentences: declarative (statements), interrogative (questions), imperative (commands), and exclamatory (emotions).

Verb tenses include present (e.g. I go, she eats), past (e.g. I went, she ate), and future (e.g. I will go, she will eat).
Verb aspects include simple (e.g. I go, I went), progressive (e.g. I am going, I was going), perfect (e.g. I have gone, I had gone), and perfect progressive (e.g. I have been going, I had been going).

Modality involves expressing degrees of possibility, necessity, and obligation using modal verbs (e.g. can, must, should).
Active voice (e.g. The dog bites the man) and passive voice (e.g. The man is bitten by the dog) are used to change the focus of a sentence.
