Any verb that does not end in ‐o in the regular (indicative) present tense will be irregular in the present subjunctive because, in these cases, you cannot just take the yo form and drop the o. The five verbs in this category are conjugated in tables , , , , and .
The verb dar (see Table ) has an accent on the forms that look like the preposition de to differentiate the verb forms from the preposition. In addition, the vosotros/vosotras form does not have an accent because it is only one syllable. The verb estar (see Table ) has accents on all forms except the nosotros/nosotras form because of the general rule of accentuation.
