Every part of speech
Eight jobs a word can do, the quick test for each, and where each job gets its own chapter.
You're looking at one word and need to name its part of speech. Don't reach for a memorized list: the same spelling can do different jobs (light is a noun, a verb, and an adjective in three different sentences). Find the word in its sentence and ask what it is doing there. Does it name a person, place, thing, or idea, and still sound fine with the or a in front? Noun. Does it stand in for a noun already named? Pronoun. Is it the action or state of being, the one word that changes form to show time (light, lit)? Verb. Does it describe? Ask what it's attached to: a thing or a person makes it an adjective; an action, an adjective, or another adverb makes it an adverb. Does it tie the noun after it to the rest of the sentence by place, time, or direction (under, before, with)? Preposition. Does it join words or clauses (and, but, because)? Conjunction. Does it only express a reaction, so the sentence is still complete when you cover it (wow, ouch)? Interjection.
