let’s add our stem change.
Remember, E can change to IE only

Remember, only the e in the stem can change.

 perder
If there are two e’s in the stem, the second one
always changes.
 preferir

object, querer means to love.

Pensar (To think)
The verb pensar is another very useful stemchanging verb.

¿En qué piensas? (What are you thinking

Pensar de means “to think of” (to have an opinion
about.)

Pensar que means “to think that” (in answer to the above
question, for example.)
