Introduction to Stem-Changing Verbs

●Stem-changing verbs alter their vowel in certain conjugations

●Three main types in present tense:

●e → i

●e → ie

●o → ue

●These changes occur in all forms except nosotros/vosotros

●In the present progressive, the stem change ONLY occurs with verbs that
end in -IR

E> I Stem-Changing Verbs

●Common e → i verbs:

●pedir (to ask for)

●servir (to serve)

●repetir (to repeat)

●In present progressive:

●The stem change affects the present participle, and is still e to i

●The "estar" conjugation remains regular

●Example: Ella está pidiendo ayuda (She is asking for help)

Multiple Choice

IR stem changing E to I verbs (such as "elegir", "decir", or "servir") change stem in the present progressive and then add the regular "iendo" ending

Ex: decir -> estoy diciendo

• cierto / true

• falso / false

E>IE Stem-Changing Verbs- become e>i!!!

●Some e → ie verbs:

●mentir (to lie)

●convertir (to convert)

●sentir (to feel)

●In present progressive:

●"Estar" shows the subject change

●Present participle changes e>i

●Example: (Nosotros) nos estamos sintiendo felices (We are feeling happy).

Multiple Choice

¿El novio te miente? ¡Qué horrible!

(Your boyfriend lies to you? That's horrible!)

• Sí, mira este mensaje. Él me está mintiendo ahora.
• Sí, mira este mensaje. Él me está mantiendo ahora.

• Sí, mira este mensaje. Él me está mentiendo ahora.

• Sí, mira este mensaje. Él me está mentyendo ahora.

O → UE Stem-Changing Verbs become o>u

●Common o → ue verbs:

●morir (to die

●dormir (to sleep)

●In present progressive:

●"Estar" displays the subject change

●Present participle has the stem change

●Example: Ellos están durmiendo (They are sleeping)

Multiple Choice

IR stem changing O to UE verbs (such as "dormir") change stem from O to U in the present progressive and then add the regular "iendo" ending

Ex: dormir -> estoy durmiendo

• cierto / true

• falso / false

Key Points to Remember

●Stem changes only affect the present participle

●Present participles remain regular for ar and er stem-changing verbs

●Pay attention to irregular present participles (e.g., ir → yendo)

●Practice recognizing stem-changing verbs in context
