Irregular Spanish Verbs

The verbs Ir (to go), Dar (to give) and Estar (to be) are irregular in the present tense. However, the only irregularity is in the first person yo. All other forms are the same forms of a regular "ar" verb.

Example of conjugation:

Yo voy (I go), Tú vas (You -informal- go), Él va (He goes), Ella va (She goes), Usted va (You -formal- go), Nosotros vamos (We -masculine- go), Nosotras vamos (We -feminine- go), Ellos van (They -masculine- go), Ellas van (They -feminine- go), Ustedes van (You -plural- go).

Yo doy (I give), Tú das (You give), Él da (He gives), Nosotros damos (We give), Ellos dan (They give).

Note 1: Don't forget that Él, Ella and Usted share the same form of the verb. It is the same case with Nosotros and Nosotras and with Ellos, Ellas and Ustedes.

Note 2: Ir is unique, because despite being an "ir" verb, it's endings are like those of "ar" verbs.

Note 3: Notice that the verb Estar ( to be), from our second lesson, is an irregular verb.

The verbs Poner (to put), Hacer (to do, to make), Traer (to bring), Salir (to go out, to leave) are irregular in the present tense, but only in the first person singular yo. All their other forms are regular. For example:

Most verbs that end in cer or cir are irregular in the present tense. Notice, however, that only the first person singular is irregular, and all other conjugations are regular. For example:

Note: Conocer means to know somebody or to know some place (to be familiar with). For example:

The verb Saber means "to know" (something, as in facts or knowledge), and is also irregular in the present tense but only in the first person singular yo. Otherwise, it's conjugated as a normal "er" verb.

Note: Saber means to have the knowledge of something. For example:

Yo sé donde está el supermercado. (I know where the supermarket is.)

The verb Ser (to be) is irregular in the present tense. Ser is a very unique verb, and no other verb follows the same pattern:
