Warm-up

Let's see what's already there before we add anything new — don't worry about getting it perfect.

Complete what you already know:

"If I known you were coming, I'd have cooked something nicer."

SPEAK

Say one sentence out loud about something you wish had gone differently recently. Start with "If I had known..." or "If I hadn't...".

Listen in on this conversation

Friend A: Did you get that email from the letting agency?

Friend B: Yeah — it said, "Should you have any concerns about the property, please contact us within 48 hours." So formal!

Friend A: Ha — that's just a fancy way of saying "if you're worried about anything, tell us."

Why do you think formal emails and contracts phrase things like "Should you have any concerns..." instead of the everyday "If you're worried..."? Say your own idea before you check.

Check your idea CLICK
In careful, formal, or written English, "if" can disappear altogether — the auxiliary (should, had, were) simply moves to the front instead. It sounds more polished and economical, which is exactly why it turns up in emails, contracts and official announcements, and almost never in casual chat. That formal world — plus the grammar that quietly sits underneath phrases like "insist that..." and "if I were you..." — is what today is about.
Today: the subjunctive after insist / recommend / it's essential (be, not be), the were-subjunctive (If I were..., as it were, were it not for...), and formal inversions like Should you.../Had we.../Were this to... (plus but for) — so you can read and write confidently in formal English: emails, contracts, and polished speech.

Insisting & Requiring: "We insist that she be informed"

Formal and written English — official statements, memos, contracts.

Spot the pattern

Three formal statements:

Look at the bold verbs next to "the CEO", "she" and "the tenant". What would you normally expect there instead — and what's happened to the negative in the third one? Say your idea before you check.

Check the pattern CLICK
You'd expect "resigns", "is" and "does not sublet" — but the -s disappears, and the negative loses "does" and becomes simply "not sublet". After verbs of insisting, recommending or requiring (and phrases like it's essential/vital/important), the pattern is that + subject + BASE FORM, whatever the subject is. Negative = subject + not + base form.

Honest note: in everyday British speech, people usually just say "insists that the CEO should resign", "that she should be informed", "that the tenant shouldn't sublet" — completely natural and very common. The bare subjunctive is more typically American; in British English it survives mainly in formal writing, legal and contract language.
insist / recommend / require / demand / suggest / propose + that + subject + BASE FORM
it is essential / vital / important + that + subject + (not) + BASE FORM
everyday alternative: ...that + subject + should + BASE FORM
Everyday: "The landlord says the new tenant should pay a deposit."
→
Formal: "The landlord requires that the new tenant pay a deposit."

Your turn

Type only the missing verb.

1. The committee recommends that each candidate (submit) a written statement.

2. It's vital that the alarm (not / go off) accidentally during the test.

3. Rewrite formally. Everyday: "The landlord says the new tenant should pay a deposit before moving in." Formal: "The landlord requires that the new tenant a deposit before moving in."

SPEAK

Imagine you're writing a short formal notice for your workplace or building. Say two rules out loud using "It's essential that..." or "...insists that..." with the bare subjunctive, then say the same two rules again the everyday way, with "should".

As It Were: The Were-Subjunctive

For hypothetical, unreal situations — and one fixed idiom that never changes.

Spot the pattern

Look at "were" in the first and third sentences — what's unusual about it, given the subjects "I" and "it"? Say your idea before you check.

Check the pattern CLICK
In both, "were" is used instead of "was" — even with I/he/she/it. This is the were-subjunctive: for something hypothetical, unreal, or for effect, English keeps "were" whatever the subject. "As it were" is a fixed phrase meaning roughly "in a manner of speaking" — it never changes form. "Were it not for X" is a formal, inverted way of saying "if it were not for X" — meaning "without X".

Honest note: in relaxed everyday speech you'll very often hear "If I was you..." — extremely common, and most people won't blink at it. But "were" is still the form that careful and written English expects, and the one exams and formal writing reward.
if + subject + WERE ... (all persons: I were, he were, it were)
as it were = so to speak (fixed, no change)
were it not for + noun = if it were not for + noun (= without)

Your turn

1. If she in charge, the whole policy would be different.

2. it not for the volunteers, the shelter would have shut down last winter.

3. She's turned into the office diplomat, , smoothing over every disagreement between the two teams.

SPEAK

Say a piece of advice to a friend using "If I were you...", then describe a role you or someone you know has taken on unofficially, ending the sentence with "...as it were."

Should You, Had We, Were This: Formal Inversions

Emails, contracts and polished speech — conditionals with no "if" at all.

Spot the pattern

Each sentence is a conditional with no "if" at all. What's moved to the front instead? Say your idea before you check.

Check the pattern CLICK
The auxiliary — should, had, were — jumps in front of the subject and does the job "if" normally does. "Should you require..." = "If you should require..."; "Had we known..." = "If we had known..."; "Were this policy to change..." = "If this policy were to change...". It's a formal, slightly old-fashioned-sounding pattern you meet constantly in emails, contracts and polished speech — never in casual chat.

Careful with the Had-inversion: if the base sentence already has "had" as its main verb (not just as an auxiliary), that "had" doesn't disappear — only the fronted auxiliary is new. "If I had had all the facts, I would have decided differently" inverts to "Had I had all the facts, I would have decided differently" — both "had"s stay. "Had I the facts" sounds like something from a costume drama, not modern standard English.
Should + subject + base form, ... (= If + subject + should + base form)
Had + subject + past participle, ... (= If + subject + had + past participle)
Were + subject + (to) + base form, ... (= If + subject + were (to) + base form)

One more formal alternative worth knowing: but for + noun phrase replaces a whole "if it weren't for..." clause. "But for the fire alarm test, the office would have been silent all afternoon." = "If it hadn't been for the fire alarm test, ..."

Your turn

1. Formal: " you need to change your booking, call the front desk directly."

2. Rewrite using the formal inverted form (no "if"): "If I had had more warning, I would have prepared properly."

3. Rewrite using "But for": "If it hadn't been for your feedback, I would have submitted the wrong version."

SPEAK

Imagine you're leaving a polite voicemail for a client about a delayed order. Say one sentence with "Should you...", one with "Had we known...", and one with "Were this to happen again..." — as naturally as you can.

Your Turn to Talk

Time to use today's forms in one real, polished piece of communication.

The situation

Something went wrong in a service or work situation — a delayed delivery, a double-booked venue, a mistake on a bill, a cancelled appointment. (If nothing comes to mind, invent one.)

Speak for one minute as the person responsible, apologising and reassuring the other person. Try to include:

01:00

Now put it in writing

Write a short, polished message (3–5 sentences) about the same situation, as if you were emailing the client formally. Use as many of today's forms as you can — the checker will tell you which ones it finds.

Mix It Up

Everything mixed together — you decide which form fits.

Fix the mistakes

Each sentence has one grammar mistake. Rewrite the whole sentence correctly.

1. "Should you will need any assistance during your stay, please dial 0 for reception."

2. "If had I known about the strike, half the team would have missed the meeting."

3. "The company insisted that he goes to the meeting in person."

4. "Had I more time, I would have double-checked every figure."

Which form fits?

5. "___ you need to cancel your reservation, please give us 24 hours' notice."

6. "___ she known the museum would be shut for renovation, she'd have chosen a different venue for the exhibition."

7. "It is essential that all data ___ backed up before the system update."

SPEAK

Imagine you're a manager writing a formal notice about upcoming building work. Say two rules using "insists that.../it's essential that...", one prediction using a Should/Had/Were inversion, and one sentence with "were it not for" or "but for". Give yourself a mental one-minute limit and don't stop to correct yourself.

What Do You Remember?

First, from earlier grammar

1. The basic (non-inverted) form you already know: "If she (know) about the traffic, she would have left earlier."

2. Say it out loud: what's the difference between "If I were rich..." and "If I had been rich..."? Give one example of a situation each would describe.

Compare with a possible answer CLICK
One possible answer: "If I were rich, I'd travel more" talks about an unreal situation now — a general, ongoing hypothesis. "If I had been rich, I would have travelled more" talks about an unreal situation in the past — something that didn't happen and can't be changed. Same "were"/"had" logic, different point in time.

Now, today's grammar — fresh sentences, no looking back

3. The safety inspector demanded that the site (close) immediately.

4. it not for last-minute sponsorship, the festival would have been cancelled.

5. the printer break down again, call the technician directly rather than waiting.

Think back

Which of today's forms do you think you'll actually use — in emails, at work, or in an exam? Say why you think that one will stick.

Can you now...?

At the start we said: the subjunctive, the were-subjunctive, and formal inversions, so you can read and write confidently in formal English. Tick what's true:

Anything you didn't tick — go back to that tab and try the exercises once more. They'll still check your answers.
