The Subjunctive

The subjunctive is a special verb form for things that are not real — wishes, hopes, suggestions and imagined situations. It's rarer than the everyday moods, and that's exactly why it trips students up: you don't meet it often enough for it to feel automatic, so when it does turn up, it looks a bit strange. Why were and not was? Why be and not is? The forms seem to break the rules you've just spent years learning. The trick is to realise the subjunctive isn't breaking the rules — it's using an older, special set of them, kept alive for a few important jobs. And honestly, for most of your writing, there's really only one form you need to nail.

The most common one: "were"

For an imagined or unreal situation, use were for all subjects — even I, he and she, where you'd normally say was:

If I were you, I'd apologise. I wish I were taller. She acts as if she were in charge.

Look at how were sits happily after I and she there. In ordinary past tense you'd write I was and she was — but this isn't ordinary past tense. It's the subjunctive, marking that the situation is imaginary. You're not saying something that happened; you're dreaming up something that isn't true.

Why "were" and not "was"?

Here's the simplest way to feel the difference. Was is for things that really happened: "I was late this morning." True, real, done. Were (the subjunctive) is for things that aren't real at all: "If I were a millionaire…" — I'm plainly not. So the swap from was to were is your language quietly signalling "this is imaginary." Once you hear it that way, it stops feeling like an odd exception and starts feeling like a useful little flag.

The "that… be / do" one

There's a second subjunctive worth recognising. After words like suggest, insist, essential, important and demand, English uses the bare verb — no -s on the end, even for he and she:

It's essential that she be on time. (not "is on time") I suggest that he apply early. (not "applies") The head insisted that every pupil wear the correct tie. (not "wears")

It sounds a bit formal — because it is formal — but it's completely correct. You'll spot it in rules, notices and serious writing far more than in a chat with friends.

When to use it

• Imagining something untrue → If I were…
• A wish → I wish it were…
• Comparing to something unreal → as if / as though she were…
• A demand or strong suggestion → that she be / do…

Watch out — it's mostly just "were" for you

Let me be honest about what actually matters here. For nearly all of your writing, the one to remember is were in "if I were" and "I wish I were". That single form does most of the work, and getting it right instantly makes your writing look careful. The that… be pattern is worth being able to recognise so it doesn't confuse you when you meet it, but you'll produce it only rarely.

More worked examples

• ✗ If I was in charge, I'd change the timetable. → ✓ If I were in charge, I'd change the timetable. (imaginary — subjunctive "were")
• ✓ I wish it were sunny for sports day. (a wish about something untrue right now)
• ✓ He talks as if he were the referee. (he isn't — so "were")
• ✗ I was late, so I ran. → stays ✓ I was late, so I ran. (this really happened — ordinary "was", not subjunctive)
• ✓ It is important that she be told the truth. (the bare-verb "that… be" pattern)

That fourth one is important: not every was becomes were. When something genuinely happened, keep was. The subjunctive is only for the imaginary.

You've already met the subjunctive without knowing it

Here's something that makes the whole thing feel friendlier: you already use subjunctives all the time, in little set phrases you've never thought twice about. When you say "Long live the King!" you're using a subjunctive — notice it's live, not lives. Same with "God save the King," "Be that as it may," or a friend saying "So be it." Nobody learns these as grammar; we just pick them up as whole phrases. That's proof the subjunctive isn't some foreign import you have to force into your head — bits of it are already sitting in your everyday English, keeping that old bare-verb shape alive. Recognising them helps the "that… be" pattern feel a lot less alien when it shows up in more serious writing.

Why it matters

The subjunctive is one of those small choices that quietly marks writing out as careful and grown-up. In an exam, in a formal letter, or in a story where you want the grammar to feel polished, "If I were you" lands better than "If I was you" — and markers are actively looking for exactly this kind of precision. It also helps your meaning. That flip from was to were tells your reader, in a single letter, "I'm imagining this, not reporting it." That's a lot of information packed into one tiny change. Best of all, the effort is minimal: remember were for wishes and unreal "if" sentences, and you've got the version that matters most, sorted for good.

Quick check

1. If I ___ (was / were) rich, I'd buy a boat.

2. I wish it ___ (was / were) sunny.

3. She acts as if she ___ (was / were) in charge, but she isn't.

4. Yesterday I ___ (was / were) ill, so I stayed home.

5. It's essential that he ___ (is / be) on time tomorrow.
