I'm reading a book about Spanish grammar. In the section on present indicative verbs, this statement is made: "Verbs with irregular first-person singular only; all other forms in the present are regular: ......." and it goes on to list a bunch of verbs like
caber and
traer, etc. It also includes
estar on the list. Is the present indicative conjugation for
estar really considered regular except for the first-person
estoy? So, the accents don't make it irregular:
estás, está, están, etc...
