What is a stem changing verb
A stem-changing verb is a verb that has a change in the stem. When it comes to stem-changing verbs we change the ending according to who is performing the action but we also have to change the stem.
Before we learn how to make all of those changes, let’s review the parts of a verb to make sure we are making changes where they belong.

Examples of e to ie stem-changing verbs
The verb empezar? To start, to begin.
Empezar is a stem-changing verb.
Not only are we changing the –ar according to who is performing the action, but we also have to change the stem and that’s going to be this specific e. The one I highlighted for you.
That highlighted e changes to ie in all forms except for nosotros and vosotros. Let me show you how this works.
Now, since empezar is an -ar verb, we need to remember the endings for -ar verbs which are:
o, as, a, amos, áis and an
Remember, the highlighted e changes to ie in all forms except for nosotros and vosotros.
yo → empiezo – I begin/Istart
tú → empiezas – you begin/you start
él/ella/Ud → empieza – he/she/You (f.) begin/start
nosotros → empezamos (remember no stem change in the nosotros form) – We begin/start
vosotros → empezáis (remember no stem change in the vosotros form) – You(pl.) Spain begin/start
ellos/ellas/Uds. → empiezan – They/You (pl) begin/start
Ellos empiezan la clase de español.
They begin the Spanish class.
Yo empiezo mi día a las 6:00 a.m.
I begin my day at 6:00 a.m.

The verb querer – e → ie
Querer = to want … by the way, that u is silent. Querer.
We know querer it’s an -er verb … so we need to use -er verb endings.
o, es, e, emos, éis, en
And … we know querer is a stem changer. The highlighted e changes to ie in all forms except for nosotros and vosotros.
yo → quiero – I want
tú → quieres – you want
él/ella/Ud. → quiere – he/she/You (f.) want
nosotros → queremos (remember no stem change in the nosotros form) – We want.
vosotros → queréis (remember no stem change in the vosotros form) – You(pl.) want
ellos/ellas/Uds. → quieren – – They/You (pl) want
Did you notice how we conjugated this verb? We changed the ending like a regular -er verb and in addition, we change the e in the stem to ie in all forms except for nosotros and vosotros.

He wants to speak Spanish.
Tú quieres hablar francés.
