Common mistakes

  1. Wrong: Yo extendo el brazo hacia la ventana. — Right: Yo extiendo el brazo hacia la ventana. — extender is a stem-changing verb (e → ie): the stem vowel changes in the stressed present forms, so the yo form is extiendo, not extendo.
  2. Wrong: Espero que él extiende el brazo hacia la ventana — Right: Espero que él extienda el brazo hacia la ventana — After espero que, Spanish requires the subjunctive: Espero que él extienda el brazo hacia la ventana — not the indicative Espero que él extiende el brazo hacia la ventana.
  3. Wrong: Ayer, yo extiendo un cheque al vendedor — Right: Ayer, yo extendí un cheque al vendedor — Ayer points to a finished action in the past, so it needs the preterite: Ayer, yo extendí un cheque al vendedor.
  4. Wrong: De niño, yo extendí la manta sobre la cama todos los días — Right: De niño, yo extendía la manta sobre la cama todos los días — For a repeated habit in the past, use the imperfect, not the preterite: De niño, yo extendía la manta sobre la cama todos los días.
  5. Wrong: Yo extiendo en la mano para saludar. — Right: Yo extiendo la mano para saludar. — extender takes this complement directly, with no preposition: Yo extiendo la mano para saludar.
