Common Irregular Verbs- The "(G)" Change

In the yo form of several verbs, there is a "g" that is inserted in the suffix of the conjugation.

The following verbs have an irregular "g" in the yo form:

caer	yo caigo*, I fall
hacer	yo hago, I make
poner	yo pongo, I put
salir	yo salgo, I leave
traer	yo traigo*, I bring
valer	yo valgo, I am worth

*The verbs caer, traer and verbs similar to them such as extraer(to extract) have an additional "i" before the g is placed.

These verbs are regular for the rest of the conjugation. Verbs that share these base roots exhibit the same conjugation pattern: componer(to compose), imponer(to impose), and deshacer(to undo) are just some examples.

There is yet another group of quite common "g"-changing verbs that also have further stem changes:

decir	to say, to tell
yo digo	nosotros decimos
tú dices	vosotros decís
Ud. dice	ellos dicen

tener	to have
yo tengo	nosotros tenemos
tú tienes	vosotros tenéis
Ud. tiene	ellos tienen

venir	to come
yo vengo	nosotros venimos
tú vienes	vosotros venís
Ud. viene	ellos vienen

The verb ir(to go), is conjugated very irregularly:

ir	to go
yo voy	nosotros vamos
tú vas	vosotros vais
Ud. va	ellos van

The verb ir is used to express the action of going, or to start an expression that is equivalent to is going to in English:

Marcos va a trabajar en esa tienda. Marcos is going to work at that store.
Ellos van a venir a nuestra fiesta. They are going to come to our party.
Yo voy a llevar unas cervezas. I am going to bring some beer.
