Debbie is right about this basic format for conjugating present tense verbs but there are of course some weird ones that don't fit the standard rules. To highlight a select few:

ir (to go) conjugates strangely:

yo voy (I go)
tu vas (you go)
ella va (she goes)
nosotros vamos (we go)
ellos van (they go)

tener (to have) conjugates strangley:

tengo (I have)
tienes (you have)
tiene (he has)
tenemos (we have)
tienen (they have)

ser (to be) is bizarre:

soy (I am)
eres (you are)
es (he/it is)
somos (we are)
son (they are)

and once Debbie starts getting into explaining how to conjugate other verb tenses like future perfect, past, subjunctive and whatever you call the state of do'ing' something, you will hear of such endings as:
-ieron, -ando, -ido, and so forth. Then you'll see how these 'different' verbs continue to get crazy and deviate from all rules.


This is a great node. Everyone should strive to be bilingual. Of course computer languages count.
