When you conjugate ar, ir and er verbs you remove the infinitive ending and then you add the ending that matches the subject. I think you're trying to ask how you can differentiate between ar, ir and er verbs after they are conjugated so I'll type a little example:
hablar
yo: hablo
tú: hablas Â
ella, el, usted: habla Â
nosotros: hablamos
ellos, ellas, ustedes: hablan
comer
yo: como
tú: comes
ella, el, usted: come
nosotros: comemos
ellos, ellas, ustedes: comen
vivir
yo: vivo
tú: vives
ella, el, usted: vive
nosotros: vivimos
ellos, ellas, ustedes: viven
I don't know how to explain this properly but, when you compare the three you can see the obvious differences.
