Should I use subjunctive in the clause after the words "I'd appreciate/prefer it if"?
Thanks in advance.
I must have got you a bit confused about it all, enydia.
The subjunctive has two forms - a present and past form. The present form is the same as the base form of the verb; you can see the difference to the indicative mood only in the third person singular, which has no final -s, and in the case of the verb be, which has the form be for all persons.
The past subjunctive is identical with the past tense except in the case of the verb be, which has the form were for all persons.
So if you say subjunctive, I take it for granted that you mean the present subjunctive, which is obviously different to the past subjunctive.
