Stop reaching for "if". Learn the conjunctions that let you set terms, warn, and imagine the roads not taken.
By C1 you can build all three basic conditionals accurately. The advanced skill is different: it is knowing that "if" is only the plainest of many ways to set a condition. Skilled writers reach instead for provided that, as long as, unless, on condition that, supposing and but for — each of which carries a slightly different tone, from the coldly contractual to the wistfully counterfactual.
This unit treats the conditional as a register tool. You will learn to state terms formally with provided that, to negate a condition cleanly with unless, to imagine an alternative history with but for and if it hadn't been for, to imply a whole "if" clause with otherwise or an imperative, and to blend time frames with the mixed conditional. Handled well, these choices make argument sound precise, controlled and unmistakably C1.
A cluster of conjunctions state a positive condition more precisely — and more formally — than "if". They all mean roughly "only if this one requirement is met", and they belong to careful, often written English: contracts, rules, negotiations and academic argument.
| Conjunction | Register & nuance | Example |
|---|---|---|
| provided / providing (that) | formal; emphasises a required condition | You'll get your money back provided that you keep the receipts. |
| as long as / so long as | neutral to informal; "on the single condition that" | I'll wait as long as you promise not to be late again. |
| on condition that | very formal; states an explicit term or clause | He was let back on the team on condition that he train weekly. |
Unless means "except if" or "if... not" in a single word. It introduces the one circumstance that would reverse the main outcome. It is elegant and common, but it hides a classic C1 trap: because unless already contains a negative, you must not add a second one.
| Sentence | Meaning | Note |
|---|---|---|
| We'll eat outside unless it rains. | = if it does not rain, we'll eat outside | rain is the one thing that would change the plan |
| Don't call me unless it's urgent. | = call me only if it is urgent | "unless" isolates the single exception |
| I won't sign up unless my parents approve. | = I'll sign up only after my parents approve | the negative is already inside "unless" |
To imagine an alternative history — what would (or would not) have happened without one decisive factor — English uses but for + noun and its longer relatives if it weren't for / if it hadn't been for + noun. These are the grammar of near-misses, gratitude and blame. The critical rule: but for is followed by a noun or noun phrase, never a full clause.
| Structure | Time reference | Example |
|---|---|---|
| but for + noun | present or past unreal; formal | But for the traffic, we would have arrived by six. |
| if it weren't for + noun | present/general unreal situation | If it weren't for her support, I'd give up now. |
| if it hadn't been for + noun | past unreal situation | If it hadn't been for the guard, the fire would have spread. |
Sometimes the whole "if" clause is left unspoken, because context makes it obvious. English has neat devices for this: otherwise (= if not), in that case (= if that is so), and the punchy imperative + and / or pattern that packs a whole conditional into a warning or a promise.
| Device | It means... | Example |
|---|---|---|
| otherwise | "if you don't / if that isn't so" | Leave now; otherwise you'll miss the connection. |
| in that case | "if that is true, then..." | "It's fully booked." "In that case, we'll drive." |
| imperative + and | "if you do this, a good result follows" | Trust the process and the results will come. |
| imperative + or | "if you don't, a bad result follows" | Hurry up, or we'll miss the last train. |
Supposing (or suppose) opens a hypothetical — it invites the listener to picture a situation, much like "what if". Separately, the mixed conditional lets one clause sit in the past while the other sits in the present, so a past cause can be linked to a present result (or vice versa).
| Structure | Function | Example |
|---|---|---|
| supposing / suppose (that) | raises a hypothetical for discussion | Supposing the trip fell through, what would we do? |
| past cause → present result | "if" + past perfect, then "would" + base | If she had studied medicine, she would be a doctor now. |
| present cause → past result | "if" + past simple, then "would have" + V3 | If he weren't so proud, he would have apologised yesterday. |
These are the errors that still surface in otherwise strong C1 writing. Each one is a conditional slip — a wrong conjunction, a wrong form, or a smuggled second negative. Audit your own writing against every row.
| Wrong ✗ | Right ✓ | Why? |
|---|---|---|
| Unless you don't book early, you'll miss out. | Unless you book early, you'll miss out. | "unless" already means "if not"; a second negative reverses it. |
| But for you warned me, I would have signed. | But for your warning, I would have signed. | "but for" takes a noun phrase, not a full clause. |
| I'll help provided that you will share your sweets. | I'll help provided that you share your sweets. | "provided that" takes the present, not "will", for a future condition. |
| Supposing it will snow, would you still drive? | Supposing it snowed, would you still drive? | "supposing" opens a hypothetical, so use the past, not "will". |
| If I had taken the job, I would have been richer today. | If I had taken the job, I would be richer today. | "today" needs a present result: a mixed conditional, not the third. |
Two friends discuss whether the school talent show will go ahead. Read it twice and watch the conditional system work: a formal condition with as long as, a clean negation with unless, a counterfactual with but for, a hypothetical with supposing (blended into a mixed conditional), and an implied condition with otherwise.

But for a single phone call one November night, the town of Aldergrove would almost certainly not exist today. Since that story is rarely told, few residents realise how much once hinged on one condition being met. Had it not been for a junior engineer named Petra Kovac, the valley's ageing dam would have failed, and thousands of homes would have been swept away.
Aldergrove had grown up in the shadow of that dam without ever quite understanding its dependence on it. Built in the 1930s to tame a river that had once flooded the valley every spring, the structure had come to seem as permanent as the hills it was wedged between. Generations had picnicked on its grassy embankment, wholly unaware that the concrete beneath them was quietly ageing, its reinforcing steel corroding season by season. To the townspeople the dam was scenery; to the handful of engineers charged with its upkeep it was a responsibility that grew heavier with every passing decade. Were the wall ever to give way, the water it held back would reach the first houses in under twenty minutes — a fact recorded in a report that almost no one had troubled to read.
Kovac had noticed hairline cracks during a routine inspection. Her supervisors, however, were dismissive. The dam was perfectly safe, they insisted, as long as the reservoir was never allowed to overfill. Whereas she saw a structure on the point of failure, they saw only an anxious newcomer. Unless she could prove imminent danger, they would not authorise an emergency release; provided that the autumn stayed dry, they argued, there was nothing whatever to fear.
What set Kovac apart was not superior instinct so much as a stubborn refusal to be reassured. Fresh from her training, she had not yet learned to trust the comforting arithmetic that older engineers recited whenever the subject of the dam arose. To their eyes the cracks were cosmetic, the inevitable blemishes of an old but fundamentally sound structure; to hers they traced a pattern, fanning outward from the base in a way that spoke of stress rather than mere age. She measured them, photographed them, and returned a week later to find several of them fractionally wider. Had anyone else logged those measurements, they might well have been filed and forgotten. Because she kept returning, however, a record slowly accumulated that would ultimately prove impossible to dismiss — even if, for the moment, no one in authority was willing so much as to glance at it.
That autumn, nonetheless, was the wettest on record. Moreover, the reservoir had been kept dangerously high all season. On the night of the storm, Kovac made the decision that would define her whole life. "Open the spillway now," she told the duty officer, "otherwise the whole structure goes." Supposing she had hesitated, or waited for a permission that might never have come, the consequences would have been unthinkable; yet she did not hesitate.
The storm itself arrived with little warning. Rain that had begun as a fine drizzle in the afternoon thickened by nightfall into a relentless downpour, and the streams feeding the reservoir swelled far faster than any of the models had predicted. From the control room Kovac watched the water creep up the marker board, centimetre by centimetre, until it stood only a hand's breadth below the crest. Every instinct told her that the wall, already weakened, could not survive the pressure of a full overtopping. Whereas procedure demanded that she wait for a senior signature, the water would not wait; and so, with the telephone lines to the control centre ringing unanswered, she chose to act on her own judgement. Provided the spillway gates could be raised in time, the reservoir might be drawn down before the critical moment arrived; were they to jam, nothing she did would matter at all.
The minutes that followed stretched into something close to an hour. The duty officer, roused from a doze and confronted with an order he had no authority to question, hesitated only long enough to catch the look on Kovac's face before he threw the switches. Somewhere beneath them the great gates ground open, and a torrent that had been building all evening began, at last, to fall away down the overflow channel. Had the mechanism seized, or had the water risen even a few centimetres higher before the gates responded, the outcome might have been entirely different. As it was, the marker on the board hesitated, wavered, and then, almost imperceptibly, began to drop.
The spillway held. But for her insistence, the dam would have burst within the hour; consequently, an entire valley survived a night it never knew it had faced. Kovac was reprimanded for acting without authorisation and, notwithstanding that black mark, was quietly promoted months later. "If I had trusted the paperwork instead of the cracks," she once remarked, "I wouldn't be able to sleep today." The valley owes its existence to a warning that, but for one stubborn engineer, would never have been given.
In the months that followed, a formal inquiry pieced together what had happened, and its conclusions made uncomfortable reading for the water authority. The investigators found that the warning signs had been visible for years and that the culture of the organisation had actively discouraged junior staff from raising the alarm. Had Kovac's earlier reports been taken seriously, the panel observed, the reservoir need never have been kept so perilously high in the first place. The dam was subsequently rebuilt, this time with modern monitoring sensors embedded throughout its structure, so that no future decision would ever again rest on a single person's willingness to defy the chain of command. Yet the story that circulates in Aldergrove today is not one of concrete and sensors but of character. It is remembered as proof that expertise counts for little unless it is coupled with the courage to act on it, and that the safety of many can, on occasion, come down to whether one person is prepared to be wrong in the eyes of everyone else.

10 quick questions on advanced conditionals. Each one is marked instantly. Questions get harder as you go.
Write and submit a controlled "what if" account; your teacher will review it.
At B2 you linked ideas with however, therefore, although, whereas. At C1 you gain a sharper, more formal register with connectors such as moreover, consequently, notwithstanding, whereas and nonetheless. Used precisely — and sparingly — they signal a writer in full command of tone, and they pair naturally with the conditional forms of this unit.
| Connector | Use it to... | Example |
|---|---|---|
| moreover | add a stronger, further point | The dam was old. Moreover, the reservoir was overfull. |
| consequently | state a formal result or effect | She opened the spillway; consequently, the valley was spared. |
| notwithstanding | concede "in spite of" (very formal) | Notwithstanding the reprimand, she was later promoted. |
| whereas | draw a direct contrast between two ideas | She saw a crisis, whereas they saw a nervous newcomer. |
| nonetheless | say "even so", after a concession | The rules were clear; nonetheless, she broke them. |
| however | contrast between two sentences | The plan seemed safe. However, one condition failed. |
See the difference — the same events, written two ways:
| Flat narration ✗ | Controlled C1 narration ✓ |
|---|---|
| The dam was old. It rained a lot. An engineer opened the spillway. If she hadn't, it would have burst. She was punished but then promoted. | The dam was old; moreover, the reservoir was dangerously full. But for one engineer's insistence, it would have burst; consequently, a whole valley survived. Notwithstanding a reprimand, she was later promoted. |
A strong C1 "what if" account is not a flat list of causes. It manages conditions deliberately: it sets the scene and the stakes, states the crucial condition, imagines the alternative outcome, and reflects on what hinged on it. The skeleton stays the same — you change the content, not the shape:
| Part | What to write | Conditional form to reach for |
|---|---|---|
| 1. Orientation | set the scene and why it still matters | present perfect + "hinge on / contingent on" |
| 2. The condition | state the term everything depended on | provided that / as long as / unless |
| 3. The turning point | imagine the alternative outcome | but for / had it not been for + noun |
| 4. Reflection | judge what hinged on the decision now | mixed conditional + retrospective comment |
Write a counterfactual account of a turning point — in your own life, a public event, or a story you have researched — where the outcome depended on one condition or decision. Explore what would (or would not) have happened otherwise, and what still hinges on it now.
