Las conjunciones subordinantes unen una oración principal con otra que depende de ella y aportan el matiz: causa (because, since), contraste (although, whereas) o tiempo (when, while, before). Aquí el hispanohablante tropieza con dos cosas: la puntuación (si la subordinada va delante, coma; si va detrás, no) y sobre todo la diferencia entre although (+ oración) y despite/in spite of (+ sustantivo o -ing), que significan lo mismo pero no se construyen igual.

Cómo funcionan

Causa: because, since, as · Contraste: although, though, whereas · Tiempo: when, while, until.

Subordinada primero → coma: Although it rained, we went.

Although vs despite

ENalthough / even though + clause: Although it was cold...

ESalthough / even though + oración: Although it was cold...

ENdespite / in spite of + noun / -ing: Despite the cold..., despite being cold...

ESdespite / in spite of + sustantivo / -ing: Despite the cold..., despite being cold...

El error típico del hispanohablante

Nada de oración tras despite: despite the rain, no "despite it rained". Si necesitas oración, usa despite the fact that.

No juntes although con but: quita uno — Although it rained, we went (no "but we went").

so that (finalidad con dos sujetos)

so that + sujeto + modal — obligatorio cuando las dos oraciones tienen sujetos distintos: I lowered the TV so that my sister could read.

Mismo sujeto → usa to / in order to / so as to: I left early to catch the bus.
