go verbs go
How do I tell if a verb is a go verb or not?

If you have to tell just by looking at a verb, and you don't know how to conjugate it, there are a few things you can look for.
1.__There are no -ar "go" verbs (http://www.intro2spanish.com/verbs/conjugation/conj-go.htm).
2.__All of the "go" verbs that I can think of have a vowel sound and then a consonant sound right before the verb ending. Now, that sounds like almost all the verbs in the Spanish language, so I'll take it a little further. A lot of the pairings at the end seem to be:
"a" with "l" or soft "c," e.g., "salir" and "satisfacer"
"e" with the soft "c" or "n," e.g., "decir" and "tener"
"o" with "n," e.g., "poner"
However, I may be trying to find patterns where there aren't any, as shown by "traer," which has only a vowel before the verb ending (though that may another pairing).
3.__Learn some of the more basic "go" verbs and you'll be able to recognize a lot more.
From "tener" you have verbs like: "mantener," "detener," and "obtener."
From "poner" you have verbs like: "componer," "disponer," and "oponer."
From "traer" you have verbs like: "atraer," "contraer," and "detraer."
All of the above listed verbs are "go" verbs.
4.__Finally, as you become more familiar with Spanish, you'll start to notice that verbs sound weird and "un-Spanish" if you conjugate them regularly and recognize that they'll probably have a different form. 
If the 1st person indicative ends in go, it's a go verb, otherwise it's not.
I don't know if this a complete list of GoGo verbs - they are the only ones I know.
