It is important to break down the process of conjugating verbs in the present tense. The conjugation changes, depending on the type of verb. For example, Tener (To Have), will have a different conjugation to a verb such as Hablar (to speak). In this instance, lets take the AR ending verb, Hablar. This is conjugated as such,I speak - HabloYou speak - HablasHe/She speaks - HablaWe Speak - HablamosYou speak (plural) - HablaísThey speak - HablanIn the present tense, the main body of the verb stays the same. In this instance, the main body is 'HABL'.The ending of the verb changes, depending on the subject of the verb. The 'stem' as it is known, stays, and the ending changes.
