28 Stem-changing verbs 1

Intro:

We saw before that the verb “tener” has changes to both the stem and the ending. For example, recall that the “e” from the stem “ten-” changes to an “ie” for the “tú” form: tienes (you have). In fact, there are three primary types of “stem-changing verbs” that exist in the present tense in Spanish. Let’s take a brief look at an example of each in the “tú” form:

Three types of stem-changing verbs

Type of change	Infinitive	Stem	Tú form	Equivalent
from e: ie	querer: to want	quer-	quieres	you want
from o / u: ue	dormir: to sleep jugar: to play	dorm- jug-	duermes juegas	you sleep you play
from e: i	pedir: to ask for	ped-	pides	you ask for

The pattern for all three types of stem-changing verbs is that the “yo, tú, él-ella-Ud., ellos-ellas-Uds.” forms always undergo the stem change, but the “nosotros / vosotros” forms never do:

Stem-changing verb pattern:

Stem-change?	Stem-change?
yo (yes)	nosotros (no)
tú (yes)	vosotros (no)
él (yes)	ellos (yes)
ella (yes)	ellas (yes)
Ud. (yes)	Uds. (yes)

Stem-changing verbs: e:ie

The verb “querer” (to want, to love) is one of the most practical verbs in the language. “Querer” can be used to say what you and others want, to ask what someone wants to do, and to invite someone to do something. Don’t forget: the auxiliaries “do/does” are built into the meaning of the conjugated forms, so to ask “Do you want to…?” is simply a matter of conjugating the verb in the “tú” form “¿Quieres…?”. Another meaning of “querer” is “to love”—very practical as well!

Querer: to want; to love

Subject pronouns	Singular	Basic meaning	Subject pronouns	Plural	Basic meaning
yo	quiero	I want	nosotros/as	queremos	we want
tú	quieres	you want	vosotros/as	queréis	you want (Sp.)
él	quiere	he wants	ellos	quieren	they want
ella	quiere	she wants	ellas	quieren	they want (f)
Ud.	quiere	you want	Uds.	quieren	you want

Javier quiere viajar a España.	Javier wants to travel to Spain.
¿Qué quiere hacer Ud.?	What do you want to do?
¿Quieres bailar?	Do you want to dance?
Quieren ir con nosotros.	They want to go with us.
No queremos.	We don’t want to.
Quiero un trabajo mejor.	I want a better job.
Ella quiere mucho a sus hijos.	She loves her children a lot.

OJO: Let’s take another look at the last example: “Ella quiere mucho a sus hijos”.

Did you notice the “a” that comes right before “sus hijos”? Spanish uses a mechanism many call “the personal a” that doesn’t exist in English. Nor is the word “a” (which means “to” in other contexts) translated into anything specific in English. The idea is this: when you have a grammatical structure “subject-verb-object” and the “object” is a person or reference to a person, “a” comes right before mention of the person. A few more examples:

Examples of the personal “a”

Subject	Verb	Object
El papá	entiende	a su hijo.
The dad	understands	his son.
Los niños	creen	a sus padres.
The children	believe	their parents.

When the object is not a person, no “a” is necessary:

No personal “a”

Subject	Verb	Object
El papá	entiende	la situación.
The dad	understands	the situation.

To continue with more e:ie stem-changing verbs…

Common e:ie stem-changing verbs

calentar	to heat up	encender	to turn on, to light
cerrar	to close, to shut	entender	to understand
comenzar	to begin, to start	mentir	to lie
confesar	to confess	pensar	to think
convertir	to convert	perder	to lose
defender	to defend	preferir	to prefer
empezar	to begin, to start	querer	to want, to love

OJO: for the three-syllable verbs from the list above (em-pe-zar / pre-fe-rir), the e:ie stem change always occurs in the middle, or with the second syllable: the second “e” of “em-pe-zar / pre-fe-rir” undergoes the stem change.

¿Cómo se dice…?:

Grammar Details:

#1 from above: Ella prefiere estudiar con sus amigos.
Did you remember to conjugate the first verb (prefiere) and leave the second (estudiar) in the infinitive?

#2 from above: ¿A qué hora empieza la clase de español?
A thing, in this case a class, is the subject of the sentence and one thing is always conjugated in the él/ella/Ud. (first person-singular) form of the verb.

#4 from above: Por lo general, las tiendas cierran a las nueve de la noche.
To express am/pm with time, use the expressions: “de la mañana” for am, and “de la tarde” and “de la noche” for pm.

#5 from above: ¡Mateo no miente!
Spanish uses an upside-down exclamation mark to begin the sentence.

#6 from above: ¿Por qué no entienden ellos?
When we form a question that elicits information, the position of the subject pronoun (ellos), if used, frequently follows the conjugated verb.

#10 from above: Yo siempre defiendo a mi hermano menor.
“Menor” is an adjective, and so it follows the noun it modifies: “hermano”. “Siempre” is an adverb and its position is flexible: it could follow the verb “defiendo” or it could also appear at the end of the sentence. Also, did you remember to insert the personal “a” before “mi hermano menor”?
