"Piensa"

Question

My book says to say to someone "Think" it's piensa. But the rule is if it's an -ar verb and a second person familiar imperative to change the a to an e so it ought to be Piense. Does the rule not work in this case?

Answer 1

Yes, sorry about mixing them up. I mentioned 2nd and 3rd person as that is the way they appear on conjugation lists. I sometimes confuse formal as talking with someone you know, when it is actually the other way round.

Answer 2

De nada.

Se dice "Gracias a ustedes dos."

Answer 3

Gracias a dos de ustedes.

Answer 4

Yes, Eddy just got them switched around. Also, neither is third-person (which would be he, she, or they).

Answer 5

Ahhh--it's the formal thingee. But isn't the formal piense and the informal peinsa.

Answer 6

It sounds as if you have misread the instruction. When you are using the formal or informal imperative it should go like this.
Formal - Piensa (2nd person singular)
Informal - Piense (3rd person singular)
