The parts of speech that I understand the basics of are nouns, verbs, adverbs, pronouns, adjectives, and conjunctions. The parts of speech that I am not as familiar with are the determiner, preposition, and interjection. I understand when to use a comma with a conjunction. Most mistakes with using commas and conjunctions is that people put the comma after the conjunction when they should be putting the comma before the conjunction. A comma is correctly used when there are two independent clauses and both are separated by a conjunction, with a comma before the conjunction. A conjunctive adverb is a word that is not quite a conjunction and not quite an adverb. A few examples of these would be accordingly, however, anyway, besides, and much more. They are used when making a compound sentence, or in the middle of an independent clause. A comma is used before and after the conjunctive adverb. An appositive is a word placed after another word to explain or identify it, and always appears after the word it is identifying. The word itself, and the word it is identifying are either nouns or pronouns. An appositive phrase is a phrase that consists of the appositive and its modifiers which may be phrases. Adverbs are used to enhance words and are used to modify verbs, clauses, and even other adverbs. Adverbs can appear in different places of a sentence, which can make adverbs difficult to identify. The easiest way to identify an adverb is finding a word that has the common “ly” ending.
