Common mistakes
- Wrong: Yo solda las piezas de metal. — Right: Yo soldo las piezas de metal. — The person matters: solda is the él/ella/Ud. form, while the yo form is soldo. Using the third-person form with yo is one of the most common beginner errors.
- Wrong: Ayer yo soldo la tubería rota. — Right: Ayer yo soldé la tubería rota. — The present and the preterite are different tenses: soldo is happening now, while soldé is a finished action in the past. Use the preterite with ayer.
- Wrong: Treating soldar and unir as identical in every context. — Right: Soldar means to weld, while unir means to join things together. — They overlap, but each has uses the other does not: soldar fits sentences such as Soldo las piezas de metal, while unir belongs in a different sentence. Check the meaning you want before choosing.
- Wrong: Yo soy soldado la tubería rota. — Right: Yo he soldado la tubería rota. — Spanish perfect tenses use haber, not ser: he soldado, has soldado, ha soldado. Ser plus the participle makes a passive, not a perfect tense.
- Wrong: De niño, yo soldé el marco de la puerta todos los días. — Right: De niño, yo soldaba el marco de la puerta todos los días. — For a repeated habit in the past, use the imperfect (soldaba), not the preterite. The preterite (soldé) is for one finished action.
