Parts of speech are the various types of words used to form everyday language. Here are some examples:
* Noun - the subject of the sentence
* Verb - the action
* Adjective - the description
* Interjection - an extra word added for emphasis
* Abbreviation - a shortened way to write long words
* Adverb - the adjective of verbs or other adverbs
* Pronoun - vague nouns that can replace said nouns
* Conjunction - connects sentences and clauses
* Preposition - word used before a noun or pronoun to show relation to a clause
* Article - word before a noun that determines whether or not the noun is indefinite.
There are also such things as verb tenses, which can convey a sense of either past, present, or future.
