Spanish verbs generally end in -ar, -er, and -ir. There are several differnet tenses and hence, several different ways to conjugate each verb.

I am in no way a professional Spanish speaker, I am strictly an amatuer. However I discovered this nodeshell and I will try to explain as much as I know. (Don't get too excited, I don't know all that much!)

Basic Rules for conjugation of Spanish verbs:
1) remove the -ar/-ir/-er
Ie. hablar (to speak)
hablar -ar = habl

2) add the appropriate ending for the corresponding subject
(See chart below)
Ie. I speak, Subject = I, ending = o
habl + o = hablo = I speak.

Present Tense Conjugation:
Subject ar er/ir I o o you(familiar) as es you(formal) a e we amos emos they an en
Examples:

Hablar - to speak aprender - to learn Hablo I speak aprendo I learn Hablas You speak. aprendes You learn Habla You speak. aprende You learn Hablamos We speak aprendemos We learn Hablan They speak aprenden They learn
