You can't say we don't need to use and then need to use. You can either say:

We don't need to use you may / can use the infinitive or;

We don't need to "can't" use followed by must use the infinitive.

Hello,

In reading one of your  lessons on Prepositions, I saw "fiarse de" i.e: fiarse de algo,  Roberto, etc.

I was surprised that "de" is used here and not "a" for a person, or "en".

1) Could you help me understand why "de" is used here?

and:

2) Can these forms be used and if so, what would they mean? and if not, why not?

fiarse en algo

fiarse a algo

Thank you,

Nicole

Do the brackets around “a” mean that it can be used at the speaker’s discretion, or its use sometimes or always required? 

Could I have said, “Os animo que vengáis” or “Me han animado comprar un perro” ?

In the writing challenge 'Melon with ham' we are asked to translate "You just need to cut some melon slices"

I wrote "Solo necesitas cortar algunas rodajas de melón" and it was corrected with "unas rodajas".

I understood these were interchangeable, and I'm yet to find any definitive to the contrary. Could someone please explain my error here?

Saludos 

?inmantada    o    imantada?
