Vosotros - modo imperativo

Question

Hi!!!, I'm very confused with Vosotros form in Modo Imperativo in Spanish. I have been doing some exercices on this and I found that it`s not correct to say: no pienséis, no recuerdéis, no cierréis, no enciendáis (so all these with changes in the subject) but no penséis, no recordéis, no cerréis, no ancendáis - are correct. All these are -AR and -ER verbs. I found also examples that with -IR verbs it's not the same. Its correct to say no pidáis, no repitáis (so with changes in the subject), but incorrect: no pedáis, no repetáis. Am I right? Is there any rule to follow about this, because I didn't find anything and these are only my observations. Any of your leads will probably help me so please answer :D:D

When you say changes in the subject, do you menan changes in the stem? - 0074b507, Jul 28, 2011

Answer 1

This negative form is taken from the present subjunctive, I will give you the rule In these which change from a single letter to two letters like the verbs you mentioned, there is no change in the nosotros and vosotros form. pensemos, penséis queramos queráis However with one that change from a single letter to another single letter than change is pereserved in the nosotros and vosotros form. digamos digáis. pidamos pidáis

Answer 2

It appears that you're right. Thanks for mentioning it, cuz I had forgotten about it as well. Here's what I found on another website (LearnSpanish). It explains the rule for forming the present tense subjunctive, which is what you're using for negative vosotros-commands.

For -ar and -er stem-changing verbs, the formula* applies except that there is no stem change in the nosotros and vosotros forms

For -ir stem-changing verbs, the formula applies except that the stem change in the nosotros and vosotros forms follows these patterns: o:ue verbs change o to u; e:ie verbs change e to i; e:i verbs change e to i.

*The formula they keep referring to is the 'indicative yo-form, minus o, plus endings' rule for forming the present subjunctive.

Answer 3

From what I can tell, all of the verbs you listed above are stem changers

Often, stem changers can give Spanish learners a problem.
