In one sentence, describe what the following article is about:

Verbs show action or indicate a state of being. As in other languages, verbs need to be conjugated to match the number of people performing them. You'll also need to put verbs in past, present, or future tense to indicate the time in which the action was performed. For example:  In the sentence, “I thought I locked the gate,” thought and locked are both past-tense verbs. In the sentence, "I want to open the door," want and open are both present-tense verbs. In the sentence, "The girls admit they lied," admit is in its plural form. Were you only talking about 1 girl, you would say, "The girl admits that she lied." An adverb describes an action or an adjective (or another adverb in some cases). Adverbs show when, to what extent, and how a specific action was performed. Most, but not all adverbs end with “-ly.” Examples of adverbs include:  How: “Sam quickly ate his lunch,” or “Bertram moodily shaved his mustache.” To what extent: “Jennie did her homework excellently,” or “The cat was very furry.” When: “Tom went to his lessons weekly,” or “Adele never cut her hair.” The “-ly” ending is usually used for adverbs that derive from adjectives (such as “hungrily” from “hungry” or “gently” from “gentle”). Adverbs that do not follow this form include “too,” “very,” “never,” and “often.” You can use adjectives to modify nouns and, occasionally, pronouns. These words answer questions about nouns like: what kind? which one? how many? Examples of adjectives include:  You are a great person. The tall man was late for the meeting. Her smelly cat ruined the house party. The iguana is a terrible pet. Your mother is a kind woman. When adjectives are used to modify pronouns, they usually need a helping verb such as is and are. For example, “They are interesting,” or “He is tall.” In rare cases, adjective forms can be used to modify another adjective (a job that is typically done by adverbs). For example, “He drove a bright red car.” Determiners are a special form of adjective that are used to provide information about nouns, such as specificity, number, and distance from the speaker. For example, if you want to indicate specificity, use a definite or indefinite article. You would use the definite article “the” when you're referring to 1 particular example of a specific noun (e.g., “the book”). Use “a” if you're referring to any example of a that kind of noun (“a book”). The most common types of determiners include:  The definite article the (singular or plural) and the indefinite articles a or an (singular) or some (plural). These articles show whether the noun they modify is specific or general. For example, “The [specific] man wanted some [general] apples.” The demonstrative adjectives, which indicate both specificity and proximity to the speaker. This (singular) and these (plural) refer to specific nouns that are close to the speaker. That (singular) and those (plural) suggest a little more distance. For example: “Put these [specific, close] books with those [specific, more distant] papers over there.” Numbers are also a form of determiner, which can specify the quantity of a noun. For example, “I have twenty-three cats in my bedroom!”
Deploy verbs to show that an action is being performed. Use adverbs to modify a verb in a sentence. Insert adjectives to modify and add information to nouns. Use articles and other determiners to introduce and define nouns.
