E to D Stem Changes in Spanish Future Tense

In Spanish, certain verbs undergo an E to D stem change when conjugated in the future tense. This change involves adding a ‘d’ to the infinitive before attaching the future tense endings. Understanding these changes is crucial for correctly expressing future actions or states with these verbs.

Formation

  1. Remove the final ‘e’ from the infinitive (for -er verbs) or the final ‘ir’ (for -ir verbs).
  2. Add ‘d’ to the stem.
  3. Add the future tense endings: -é, -ás, -á, -emos, -éis, -án.

Affected Verbs

The following verbs and their compounds undergo this stem change:

  1. Tener (to have) → tendr-
  2. Venir (to come) → vendr-
  3. Poner (to put) → pondr-
  4. Salir (to leave) → saldr-
  5. Valer (to be worth) → valdr-
  6. Poder (to be able to) → podr-

Examples of Conjugations

Let’s conjugate ‘tener’ (to have) in the future tense:

  • Yo tendré (I will have)
  • Tú tendrás (You will have)
  • Él/Ella/Usted tendrá (He/She/You formal will have)
  • Nosotros/Nosotras tendremos (We will have)
  • Vosotros/Vosotras tendréis (You all will have)
  • Ellos/Ellas/Ustedes tendrán (They/You all formal will have)

Compound Verbs

Compound verbs formed from these base verbs also follow the same pattern. For example:

  • Contener (to contain) → contendr-
  • Detener (to detain) → detendr-
  • Mantener (to maintain) → mantendr-
  • Obtener (to obtain) → obtendr-
  • Retener (to retain) → retendr-
  • Sostener (to sustain) → sostendr-

Usage Examples

  1. Tener (to have):
    • Mañana tendré más tiempo libre. (Tomorrow I will have more free time.)
  2. Venir (to come):
    • Ellos vendrán a la fiesta el sábado. (They will come to the party on Saturday.)
  3. Poner (to put):
    • Pondremos la mesa antes de que lleguen los invitados. (We will set the table before the guests arrive.)
  4. Salir (to leave):
    • Saldré de casa a las ocho de la mañana. (I will leave home at eight in the morning.)
  5. Valer (to be worth):
    • Este coche valdrá mucho más en unos años. (This car will be worth much more in a few years.)
  6. Poder (to be able to):
    • No podré asistir a la reunión mañana. (I will not be able to attend the meeting tomorrow.)

Key Points to Remember

  1. These changes only occur in the future tense and the conditional tense (which is formed similarly).
  2. The endings remain regular (-é, -ás, -á, -emos, -éis, -án); only the stem changes.
  3. This change applies to all persons and numbers of the conjugation.
  4. Memorizing these six base verbs and recognizing their compounds will cover most cases of this stem change.

Understanding these E to D stem changes will significantly improve your ability to express future actions accurately in Spanish, especially with these common and important verbs.
