Conjugation is the way verbs change their form to show who is doing the action and when it happens. When you say “I walk,” “she walks,” or “they walked,” you're using different conjugations of the verb “walk.”

In English, conjugation is fairly simple. Most verbs just add an “s” for third person (he/she/it) and “-ed” for past tense. But irregular verbs like “to be” show why conjugation matters: you say “I am,” “you are,” and “she is,” not “I be” or “she be.” Each form is a different conjugation.

Many other languages have much more complex conjugation systems. In Spanish, a single verb might have dozens of different forms depending on who's doing the action, when it's happening, and whether it's a fact or a possibility. A Spanish student memorizing all the conjugations of common verbs is learning the backbone of how the language works.

When you conjugate a verb, you're connecting its core meaning to the specific situation where it's being used.
