The pattern rule

Go-verbs are regular in most forms but have an unexpected -go ending in the yo present indicative. The -go ending also creates irregularity throughout the present subjunctive (since the subjunctive is built on the yo present stem). Some go-verbs combine with stem changes in other tenses.

Frequently asked questions

What are go-verbs in Spanish?

Are go-verbs irregular in other tenses?

Some go-verbs have additional irregularities. Tener, poner, salir, venir, and haber have irregular future/conditional stems (tendré, pondré, saldré, vendré, habré). Decir, traer, and hacer have irregular preterite stems. The imperfect is usually regular.

How does the go-verb irregularity affect the subjunctive?

Because the present subjunctive is formed from the yo present stem, all go-verbs are irregular throughout the present subjunctive. Hago → haga, hagas, haga, hagamos, hagáis, hagan. Tengo → tenga, tengas, tenga, tengamos, tengáis, tengan.
