verbs like venir and tener where only the yo-form is different, what are these verbs called and could someone list them. thanks

Answer 1

verbs that are irregular in the "yo" form:

salir = salgo
decir = digo
hacer = hago
estar = estoy
poner = pongo
venir = vengo
caer = caigo
tener = tengo
oír = oigo
traer - traigo

Although I may not have all of them and they are not in alphabetical order, if you go to the back of any good Textbook, in the Appendices, you will find irrgegular verbs listed.
