Appendix: Irregular and Problematic Verb Stems in the Present Tense


The purpose of this tool is to help you find the meaning of unusual verb forms, those that would not usually be found in a dictionary. Both the infinitive and the meaning are provided.

Verbs whose infinitives you should be able to construct and look up are NOT included in this list. These are:

Many verbs combine a "really irregular" form with other peculiarities. Also, verbs frequently have both irregular and regular forms in the same tense. For example, tengo is fully irregular, tienes, tiene, and tienen have a diphthong in the stem, but tenemos and tenéis are completely regular. This table does not include the regular or the diphthong forms.

If the irregularity is found only in the first person singular, it is indicated as "1s pres." If it is found in multiple forms of the present tense, usually those with the stress on the stem (the three singulars and the third person plural) it is marked simply "pres."

Abbreviations used: p = plural; pres = present; s = singular; str = forms with stress on stem (singulars and 3rd person plural).
