1st principal part + se + personal endingsBecause the "s" of the infix "se" will be intervocalic, it changes to an "r," hence giving the appearance of the regular active infinitive ending "-re". The personal endings are those you use in the present system. (Use "-m" instead of "-o" in the first person singular.) So for the first conjugations, the forms look like this:
lauda + se + m = laudasem - laudarem lauda + se + m = laudases - laudaresLet's have a look at the imperfect subjunctive in all its forms in all the conjugations.

You can think of it this way if you wish, provided that you're aware that this understanding will have to be revised in the near future.
Wheelock also tells you that the imperfect subjunctive is used in subordinate clause when the verb of the main clause is a past tense. That's ture, but don't worry about it for now. You should just be alerted to the fact that, just like participles and infinitives, verb in the subjunctive mood don't have absolute tense, but rather they express time relative to the tense of the main verb. This will all be explained in Chapter 30. Your task in this chapter is to learn to recognize an imperfect subjunctive when you see it.
es + se + m = essem SUM, ESSE PRESENT IMPERFECT 1st _______________ _______________ 2nd _______________ _______________ 3rd _______________ _______________ 1st _______________ _______________ 2nd _______________ _______________ 3rd _______________ _______________As you no doubt recall, the verb "possum" in Latin is a compound of the adjective "pot-" and the verb "sum". If you add the "pot-" the present subjunctive of "sum," the "t" of "pot-" will always assimilate to "s". Since all the forms of the present subjunctive of "sum" begin with "s". The imperfect subjunctive of "possum" is best thought of as the present infinitive plus personal endings -- the present infinitive of "possum," that is, which is "posse". Write out the present and imperfect subjunctive of "possum".

In the positive result clause, when "ut" is used as the subordinating conjunction, you may think that some confusion between a purpose and a result clause is possible: they're both introduced by "ut" and have a subjunctive verb. This is true in theory, but in practice it happens rarely. If you see "ita," "sic," "tam," or "tantus, -a, -um" in the main clause and an "ut" clause, then you know for certain that the "ut" clause is a result clause. In the majority of cases, result clauses are anticipated somehow in the main clause. There is no possibility of confusing a negative purpose clause with a negative result clause. Negative purpose clauses are introduced with "ne;" negative result clauses start with "ut" and then negate the verb in the clause with "non," "numquam" etc., or by using a negative pronoun such as "nemo".
ita, sic, tam The adverbs which anticipate result clauses are not entirely interchangeable. "Sic" is used primarily to qualify verbs: "Id sic fecit ut..". The other two, "ita" and "tam" can qualify verbs, adjectives or other adverbs: "Via erat tam [ita] longa ut..". or "Tam [ita] male scripserunt ut..". or "Id tam [ita] fecit ut..". tantus, -a, -um This adjective for some reason always throws students off at first. It means basically "so great" but some flexibility is required to get this over into smooth English. Study carefully the way this adjective is used. quidem It's an adverb meaning "indeed, certainly," and is postpositive (it's never the first word in a sentence or clause.) This poses no problem. But the expression "ne...quidem" is sometimes difficult to spot. "Ne X quidem" means "not even X". Watch out for this. When you see "quidem," check to see whether there is a "ne" one word back. If you miss this construction, you'll mess up the sentence badly.01/10/93
