Expressing cause (como)

Expressing cause with como

You already know como as "how" or "like", but it has another use. Start a sentence with como ("since" or "because") to state the reason for an event before describing its outcome.

since (cause, sentence-initial)
como
Since the prince is not magical, the princess helps him.
Como el príncipe no es mágico, la princesa lo ayuda.
Since the dragon is in the tower, we cannot escape.
Como el dragón está en la torre, no podemos escapar.

Narrating cause and effect

When you start a sentence with como, separate the cause from the effect with a comma. This structure is perfect for telling fairy tales where one magical event causes another.

Since he could not break the spell, he didn't rescue the prince.
Como no pudo romper el hechizo, no rescató al príncipe.
Since the toad sang, the giant was quite afraid.
Como el sapo cantó, el gigante tuvo bastante miedo.
Since the spell worked, we managed to escape from the tower.
Como el hechizo funcionó, logramos escapar de la torre.
Since we entered the magical forest, the spell ended.
Como entramos en el bosque mágico, el hechizo terminó.

Como or porque?

Both give a reason, but they sit in different places. Como always opens the sentence, and the result follows after a comma. When the reason comes second, use porque instead:

  • Como el dragón está en la torre, no podemos escapar.
  • No podemos escapar porque el dragón está en la torre.

Never start the second half with como: no podemos escapar como el dragón… is wrong.
