the tricky A

[Maaz]

in Fluenz it says "Voy a intentar vender su casa" I thought according to the pattern so far it should have been "Voy a intentar a vender su casa"

there must be a rule to this that I might have overlooked. Could somebody explain the difference please.

Great question! In Spanish, when two verbs appear together, usually the second one goes in the infinitive form without “a”. So in this case, the correct form is “Voy a intentar vender su casa.”

The reason is that “intentar” is a verb that doesn’t require a preposition before another verb — it connects directly to the infinitive (intentar + infinitive). That’s different from other verbs like aprender or empezar, which do require a preposition: “Aprendí a nadar” or “Empezó a trabajar.”

So the pattern is:

intentar + infinitive → Voy a intentar vender su casa

aprender a + infinitive → Aprendí a vender casas

Hope that clears it up!
