Talking about the Present: Irregular Verbs in the Present Indicative II

Three important irregular verbs that share a common conjugation pattern are estar -- to be, dar -- to give and ir -- to go. Another important irregular verb is ser -- to be.

	ESTAR	DAR	IR	SER
yo	estoy	doy	voy	soy
tú	estás	das	vas	eres
él/ella, Ud.	está	da	va	es
nosotros/as	estamos	damos	vamos	somos
vosotros/as	estáis	dais	vais	sois
ellos/ellas, Uds.	están	dan	van	son

Even though these verbs are "irregular", if you know the endings for estar, you also know the endings for dar and ir! Note, however, the absence of accents in the conjugations of dar, ir and ser.

Here are five important verbs that are irregular only in the yo form:

CONOCER -- to know someone	yo conozco
HACER -- to make/to do	yo hago
PONER -- to put/to place	yo pongo
SABER -- to know information	yo sé
SALIR -- to leave/to go out	yo salgo

Only the yo form is irregular; the rest of the these verbs' conjugations are completely regular.


Some verbs are irregular in more than one way:

TENER -- to have        (irregular in the yo form and stem-changing as well):

yo	tengo          I have, etc.
tú	tienes
él/ella, Ud.	tiene
nosotros/as	tenemos
vosotros/as	tenéis
ellos/ellas, Uds.	tienen

Note that compound forms of irregular verbs follow the irregular pattern of the basic irregular verb:

DESCONOCER -- to not know something	yo desconozco
REHACER -- to make over/to do over	yo rehago
DISPONER -- to dispose/lay out	yo dispongo
DETENER -- to detain/arrest	yo detengo, tú detienes, etc.
