Conjugating a verb just basically means changing the form of the verb to match the person it's talking about ("subject"). In languages like Spanish, English, and French, conjugating is especially important. For instance, in English, we have the verb "to be". English verbs can be pretty regular, meaning they don't change form too much as you conjugate them. But "to be" is notoriously irregular because a lot of the forms are different. Let's conjugate "to be": I --> am You --> are She/he/it --> is We --> are They --> are The base (original) form is called an infinitive, and that's "to be", just like that. The conjugated forms are the "are", "am" - etc. Spanish and English both have patterns with how you conjugate verbs, and in my opinion the Spanish system is quite intuitive (able to allow you to guess) once you know the basics. For example, we have "ser", which is one form of "to be" in Spanish. All Spanish verbs end in -ir, -er, or -ar. This is again the infinitive. Yo --> soy Tú --> eres Usted/ella/él --> es Nosotros --> somos Vosotros --> sois Ustedes --> son In other languages, the form of "to be" doesn't change according to person. But like I said before, conjugating allows you to tell what person you're talking about ("I", "him", "they"). If you get the form wrong, what you say won't make any sense. Hopefully that helped!

When you conjugate a verb you must take into a consideration this: there are two type of verbs: regular verbs and irregular verbs. REGULAR VERBS : lexeme is very important here, so it is the accent, ending of verb and combinatios of vowels in the verb. Morpheme is important too. IRREGULAR VERBS: These have the own conjugation and you have to learn it by heart. EXAMPLE: the verbs end in IAR /UAR KEEP THE LEXEME IN THE CONJUGATION AND YOU ADD THE MORPHEME A/O/AS/AN/ AMOS. VERB: Bailar, yo bailo, tú bailas, él baila, ella baila, ellos bailan, THE LEXEMA IS BAIL AND IT DOESN NOT CHANGE IN THE CONJUGATION.

I tried to explain it to you in the most clear and simplified way posible, I hope it will useful for you.
