Every complete sentence in the English language requires the use of a verb. While verbs share and describe what subjects are doing, they’re much more than simply just “action words.” Learn about various types of verb structures, tenses, forms, and patterns in our free, extensive guides on verbs.


If you speak or write about people, places, things, or ideas, then you probably use adjectives! Adjectives describe nouns and pronouns and there are a whole slew of them to choose from in the English language. While fun to explore and apply, adjectives, just like other parts of speech, have tons of rules and conventions. Learn about proper usage of possessive forms, demonstrative adjectives, and more in our complete guide on adjectives!

From relative pronouns, to reflexive, and objective, we have it all, complete with clear descriptions and examples. Check out our handy guides on pronouns below!


We use nouns every single day, in every sentence we speak or write. In fact, nouns were probably one of the first parts of speech you studied in elementary or primary school.

Possessive nouns, collective nouns, abstract and concrete nouns are no sweat thanks to our trusty reference pages, stocked with examples and clear explanations.
