If I Was vs If I Were (Subjunctive)
One quiet word marks careful, polished English apart from casual speech — learn exactly when an unreal “if” needs “were” instead of “was”.
Grammar › Commonly Confused Words › If I Was vs If I Were
The rule in one sentenceIn hypothetical, unreal “if” clauses, careful English uses the subjunctive were for every subject — including I/he/she/it (If I were you…) — while was stays for ordinary, real past facts.
What’s the difference?
Normally, past-tense “be” is simple: I/he/she/it was, we/you/they were. But there’s one special situation where “were” takes over for every subject, even “I” — and it has nothing to do with grammatical number.
When an “if” clause describes something imaginary, impossible, or contrary to fact, English switches to a leftover form called the subjunctive, and the subjunctive of “be” is always were: If Immortal Beloved were remade today, would it use AI-generated visual effects? The film hasn’t actually been remade — the whole idea is hypothetical, so “were” is expected, not “was”.
Compare that with an “if” clause describing a real, repeated fact about the past — nothing imaginary about it. Here, ordinary past-tense “was” is correct: If Straight Outta Compton was praised for its performances, critics still debated its portrayal of real events. This describes something that genuinely, factually happened; it isn’t a fantasy scenario, so it keeps the normal past simple.
🎬 Compare: “If Alan Rickman were alive today, he would still be transforming into unforgettable characters” (impossible — he passed away in 2016, so the subjunctive “were” is required) vs. “If Marlon Brando was late to set some mornings, the crew adjusted the schedule” (a real, ordinary fact about how filming worked, so plain past “was” is correct).
The most famous surviving example is the fixed phrase “If I were you” — advice built entirely on an impossible premise, since you can never actually become someone else. This lesson focuses narrowly on the was/were choice; for the wider pattern of hypothetical “if” clauses with “would”, see our Second Conditional lesson.
How to build it
Hypothetical → were (every subject)
If 8 Mile were remade as a horror film, would it still feel authentic to Detroit’s hip-hop scene?
Real past fact → was (normal past)
If Ray (2004)’s biopic approach was successful with audiences, similar music biopics soon followed.
The fixed phrase “If I were you”
This phrase is the last place the subjunctive stubbornly survives in everyday English — “If I was you” is widely heard but still marked as an error in careful writing.
If I were you, I’d watch the director’s cut of Blade Runner 2049 before the theatrical version.
When to use which
Use “were” for…
- Impossible or contrary-to-fact situations: If Buster Keaton were making films today, silent comedy might look completely different.
- Advice with “If I were you”: If I were you, I’d rewatch The Village before any sequel talk starts.
- Wishes about the present: I wish Robin Williams were still making films.
Use “was” for…
- Real, repeated facts about the past: If Marlon Brando was unhappy with a script, he’d rewrite his own lines.
- Genuine first-conditional possibilities: If the trailer was well received, the studio greenlit a sequel.
- Informal, spoken-style “if I” sentences — common in casual conversation, but not in edited writing.
Signal words
These phrases almost always travel with the subjunctive “were”.

Common mistakes
❌ If I was you, I’d rewatch The Village before the sequel rumours start.
✅ If I were you, I’d rewatch The Village before the sequel rumours start.
This is the classic fixed subjunctive phrase — it’s always “were”, however informal the sentence sounds.
❌ If Alan Rickman was alive today, he would still be transforming into unforgettable characters.
✅ If Alan Rickman were alive today, he would still be transforming into unforgettable characters.
This imagines something impossible — Rickman passed away in 2016 — so it needs the subjunctive “were”.
❌ If Marlon Brando were late to set some mornings, the crew adjusted the schedule.
✅ If Marlon Brando was late to set some mornings, the crew adjusted the schedule.
This describes a real, repeated past situation, not an imaginary one — “were” here is a hypercorrection; plain “was” is right.
British vs American note: In casual speech on both sides of the Atlantic, “was” quietly replaces “were” almost everywhere except “If I were you”, which resists the shift even in relaxed conversation. Formal writing and exams still expect “were” throughout.
Exceptions & tricky cases
1. “As if” and “as though” follow the same rule. When the comparison is impossible, they take “were” too.
✅ He talks about Double Indemnity as if he were there in 1944, even though he wasn’t even born yet.
2. “Wish” clauses about the present always take the subjunctive. Wishing for something untrue right now needs “were”, not “was”.
✅ I wish the original Mad Max trilogy were still the only canon.
3. This is only one piece of the wider second-conditional pattern. The was/were choice sits inside the larger “if + past, would + verb” structure — see our Second Conditional lesson for the full picture, including subjects other than “be”.
4. In everyday film dialogue and casual speech, “was” is extremely common even in clearly hypothetical sentences. Native speakers hear both forms constantly; “were” simply marks the more careful, edited register that essays and exams expect.
Practice: choose was or were
Eight quick questions. Ask yourself: is this real, or impossible?
1. If I ___ you, I’d watch the director’s cut of Blade Runner 2049 first.
Fixed subjunctive phrase — always “were”.
2. If Alan Rickman ___ alive today, he would still be transforming into unforgettable characters.
Impossible — Rickman passed away in 2016 — so it’s the subjunctive “were”.
3. If Ray (2004)’s biopic approach ___ successful with audiences, similar music biopics soon followed.
A real, repeated past fact, not imaginary → ordinary “was”.
4. If Marlon Brando ___ late to set some mornings, the crew adjusted the schedule.
A genuine, factual past habit → ordinary “was”.
5. If Immortal Beloved ___ remade today, would it use AI-generated visual effects?
Immortal Beloved hasn’t been remade, so this is a hypothetical situation → “were”.
6. I wish Robin Williams ___ still making films.
“Wish” about an untrue present situation → subjunctive “were”.
7. He talks about Double Indemnity as if he ___ there in 1944, even though he wasn’t even born yet.
“As if” describing something impossible → “were”.
8. If Buster Keaton ___ making films today, silent comedy might look completely different.
Keaton died in 1966 — a hypothetical impossible today → “were”.
