Comyn once said:

> Conas ta tu?

Aonghus replied

You need to put a fada over the "a" in "tá" the word is pronounced "taw" (ryhmes with "paw") without it it would sound like "tah"

So

Q: Conas tá tu?
A: Tá mé go maith
(Tá mé can also be contracted to "Táim")

aside from that, if you are adressing more then one
person, which I assume you are, you must you the
plural form of "you" which is "sibh" (pronounced
"shiv" - like a prison made knife)

So:

Q: Conas tá sibh
A: Tá sinn go maith. (We are good)
agus tusa féin?
(and you (emphatic form) yourself?

Dairchan added to what Aonghus said;

The verb 'Tá" means literally, 'to stand'. When you ask a person 'Conas tá tú? ' you would be literally asking, How are you standing, or what is your stance or (maybe) status - the implied meaning being, How are you doing?

The reply "Tá mé go maith" simply means, 'my standing is good' or
perhaps, 'I stand well' (I think in modern day english, the closest literal approximation may be 'my status is good' or something like that. The meaning to be taken is simply 'I am doing well'.

The same is true when addressing multiple persons, as in "Conas tá sibh?" - (How are ya'll doing? - in english there are perhaps 10 to 15 personal pronouns... in irish there are at least 116 - we conjugate personal pronouns, also... so speaking to a single person and speaking to multiple persons changes the grammar).

Sin é, cibé ar bith! (That's that, anyway! ((lit: that's that,
whichever at all!)) )

Le meas (with respect)
Slan go foill! (So long for now)
