[rvegagold]

The grandma wraps her grandson in a blanket

[jonthedrummer]

Agreed. We use the possessive in this sense in English. It should be accepted. I hope you reported it.

[Quarfindo]

Does envolvar specifically mean "to envelop", as in to wrap/roll up, or can it also mean to cover in general?

[Paulenrique]

Yes, it has both meaninds.

[kwneal]

Would "neto no cobertor" also be correct since "no" is a contraction?

[Paulenrique]

no = in/on/at the.

[IsaacSmithUPM]

Is "num" a real contraction? Does it mean "em um"?

[Paulenrique]

Yes, it is official. Both num and numa are correct.

Why is 'A vó' not accepted?
