In speech it is everywhere, and in some sentences it is right: if I was rude, I am sorry. When the sentence imagines something untrue, like if I were a bird, edited writing expects were. The test is whether the if-clause could be true.

Why does the subjunctive use the plain verb after insist or require?

English keeps an old form for demands and suggestions. The teacher requires that each student sign the form uses sign, not signs, because the signing has not happened. It is still being asked for.

Is would have part of the subjunctive?

Would have is the result half of a past sentence that did not happen: if we had left sooner, we would have made it. The if-clause carries the subjunctive, and the two halves travel together, so this sheet practices both.

The subjunctive mood is the verb form for things that are wished for, imagined, or demanded, not stated as fact. It shows up as were after if, wish, and as if, as the plain verb after insist that or it is vital that, and as had plus a participle for the past. Eighth graders write the form on the line.

How to teach this

Four sentence frames work better than a rule about mood: if I were, I wish it were, she insists that he go, if we had gone. Most students already hear these, even if they would say was when talking. Put the frames on a card and have your student test each item against them. The that-clause items are where the practice pays off, because the plain verb looks like a mistake to a student who has spent years adding -s. Singular subjects make it visible: that the dog stay, not that the dog stays. For the past items, have your student ask whether the thing actually happened. If it did not, the sentence needs had or would have.

Watch for: Was is not always wrong after if. If he was at practice, he saw the fight talks about something that may be true. Were is for what is not true: if he were taller. The plain verb after insist that or it is essential that is not an agreement mistake. Every player arrive is correct because the sentence demands something that has not happened yet. Would of is not a verb form. It comes from hearing would've, and in writing it is always would have.
