What are the different between regular and irregular verbs in past? Explain and give examples about the rules.

Verbos regulares a aquellos que forman el pasado agregando el sufijo ‘ed’ o ‘d’ a la raíz del verbo
example:

act	Acted	Actuar	id
add	Added	Sumar, añadir	id
aid	Aided	Ayudar	id

Irregular verbs form the past and past participle irregularly do not follow any rules to form the past, so they must learn "change vowels

Example:

arise	arose	arisen	surgir
awake	awoke	awoken	despertar(se)
bear	bore	borne	soportar
beat	beat	beaten	golpear
