Hi :

I've been studying spanish for a while. I have a question particularly the verb CABER. What is the Present Subjunctive of CABER in yo/tú/el/nos/vos/ellos forms. Of what I've learned that Present Subjunctive is formed by starting with the yo form of the present indicative, drop the -o ending and add the Present Subjunctive endings.

For the case of the verb CABER, since the present indicative yo form is QUEPO, is the following are correct?

yo form = quepa nosotros = quepamos

tú form = quepas vosotros= quepáis

el form = quepa ellos/ellas= quepan

or the following are the correct one, by just using the stem CAB?

yo form = caba nosotros = cabamos

tú form = cabas vosotros= cabáis

el form = caba ellos/ellas= caban

Thanks in advance.


The first group of forms is the correct one, i.e., quepa, quepas, quepa, etc.

A note: it's "él" is the personal pronoun; "el" is the article.


Muchas gracias.

ustedes quepan (vosotros)
Verbs that are irregular in the "yo" form of the present indicative use the same spelling changes for all forms in the present subjunctive (with a few exceptions: car, gar, zar endings and a few stem changing forms).
The verbs I am referring to (one of them "caber") are not considered irregular in the subjunctive because they follow the rule of regular verbs, such as hablar, come, vivir, ....
yo quepo (drop the "o") - quepa (add "a" to -er/ir ending verbs to form "yo" present subjunctive, then tu quepas, el/ella/Ud. quepa.... The first set of conjugation you have is the correct one. I hope this helps. Dr. Lasso.
