Vámonos
 

Can you explain the construction of vamanos to me? I understand it means let's go, but I don't understand why the s in vamos is dropped...or when to use vayamos instead. :thinking:

I would help you, but I am grammatically challenged! :(

All I remember vayamos is the subjunctive. But that's about it.

For the life of me, I cannot remember how it is called the part "nos" :duh:

So that I could try to start helping you.

Vámonos is a very common phrase, but is a degenerate form of the imperative vayámonos (1st-person plural imperative of irse, which means to leave). This is a pronominal verb. The -nos suffix is a reflexive pronoun.

To form the imperative in this person, the normal -s ending is dropped before suffixing the pronoun -nos. A similar thing happens with the 2nd-person plural reflexive pronoun, where the normal -d ending is dropped before suffixing the pronoun -os. Have a look at the charts below.

It may be easier to look at a regular verb first.

Here is levantar in the imperative:

yo	(X)	nosotros,-as	levantemos
tú	levanta	vosotros,-as	levantad
él, ella, usted	levante	ellos, ellas, ustedes	levanten

Here is levantarse in the imperative:

yo	(X)	nosotros,-as	levantémonos
tú	levántate	vosotros,-as	levantaos
él, ella, usted	levántese	ellos, ellas, ustedes	levántense

Now, here is the irregular verb ir in the imperative:

yo	(X)	nosotros,-as	vayamos
tú	vé	vosotros,-as	id
él, ella, usted	vaya	ellos, ellas, ustedes	vayan

Here is irse in the imperative (note the exception to the drop-the-d-in-2nd-person-plural rule for this verb):

yo	(X)	nosotros,-as	vayámonos
tú	vete	vosotros,-as	idos
él, ella, usted	váyase	ellos, ellas, ustedes	váyanse

I agree with Rusty. The correct expression should be "vayámonos".

I think it comes from the use of "¡vamos!" as "let's go!"

"Vámonos" is like saying in English "let's get out of here".

Vamonos (Lest go)

a bit correction:
let`s go : come on: it`s the same . Vamonos is most used than Vayamonos this is used when we are talking with a old person (gente grande).

I didn't understand you. You are telling me that the word Les't go is used to say old people or what?

I don't find sence it.

Or you explain me more because, so I won't understand you.

no , te corregí la palabra let´s go!!! y la palabra que se usa mas comun para habla con personas grandes es mejor decir vayamonos a que digamos vamonos, digo suena mas con respeto! ¨eso dije, pero no se como se dice en ingles personas mayores? ahora me entiendes!

Lee Ying:
Muestra respeto a los mayores/ancianos.
= Respect your elders.

los mayores = elders, anyone older than you
los ancianos = the elderly, the elders, old people (con cautela)

Vamanos
 

I thank you rusty , I liked your answer!!*_* now, I know new word!
