Conjugate semi-regular stem-changing (e > ie) -er verbs in El Presente (present tense)

A number of common Spanish verbs (perder, defender, encender) ending in -er are semi-regular in El Presente because the stem changes for some forms:

  PERDER
to lose
DEFENDER
to defend
ENCENDER
to switch on
 yo pierdo defiendo enciendo
  pierdes defiendes enciendes

él / ella / usted

pierde defiende enciende
nosotros / nosotras perdemos
defendemos encendemos
vosotros / vosotras perdéis defendéis encendéis
ellos / ellas / ustedes pierden defienden encienden

Notice how the vowel -e- in the stem that is closer to the end of the word becomes-ie- except for the nosotros and vosotros forms.

Look at and listen to these examples:

Yo nunca pierdo la paciencia.
I never lose my patience.

defiendes a tu hermana de todos los peligros.
You defend your sister from anything dangererous.

Ella enciende la radio todas las mañanas.
She turns on the radio every morning.

Nosotros defendemos nuestras ideas.
We defend our ideas.

Vosotros a veces perdéis el autobús.
You sometimes miss the bus.

Ellos encienden las velas de la tarta.
They light the candles on the cake.

Useful verbs that also follow this pattern are querer (to want) and entender (to understand).  You can practise them here:

Is enough information given to determine whether if the answer should be singular or plural. I used the tu conjugation and was marked wrong. I can't
