1. Impossible Hypotheticals: When Reality’s Already Screwed

Every English learner hits this wall:
"Wait, why the hell do I have to say "If I were instead of If I was? And what’s with all this would + verb stuff?"

Relax. Spanish learners are suffering too — they just suffer through si yo fuera instead.

  • English: If I were you, I wouldn’t say that to Marta. She’ll rip your head off.
  • Spanish: Si yo fuera tú, no le diría eso a Marta. Te arranca la cabeza.

👉 Same mental trick: you’re not me, I’m not you — but we’re imagining it anyway.

  • In English, were is a leftover piece of subjunctive fossil.
  • In Spanish, it’s the imperfect subjunctive (fuera) plus the conditional (diría).

Another example:

  • English: If I won the lottery, I’d tell this job to piss off.
  • Spanish: Si me tocara la lotería, me iría a tomar por culo de este curro.

Same deal: unreal past → imaginary present/future consequence.


2. Unreal Past Consequences: The Famous “What If…?” That Never Happened

This is where English and Spanish are aligned. You regret something, imagine an alternative, and wallow in self-pity.

  • English: If you had told me, we could have fixed it before it turned into this shitshow.
  • Spanish: Si me lo hubieras dicho, podríamos haberlo arreglado antes de que se convirtiera en este marrón.

📌 English: If you had told me, we could have fixed it… → past unreal condition (past perfect in the if-clause + modal perfect in the result).
📌 Spanish: Si me lo hubieras dicho, podríamos haberlo arreglado… → pluscuamperfecto de subjuntivo in the condition + condicional compuesto in the result.


2.1. Present result of an unreal past action

  • English: If I had studied more, I wouldn’t be stuck in this crappy job.
  • Spanish: Si hubiera estudiado más, no estaría pringando en este trabajo de mierda.

📌 English: If I had studied more, I wouldn’t be stuck… → If + past perfect, result in present conditional (would + verb).
📌 Spanish: Si hubiera estudiado más, no estaría… → If + pluscuamperfecto de subjuntivo, result in present conditional (condicional simple).

This is the classic mixed conditional: the past is gone, but you’re still living with the consequences.


2.2. Past result of an unreal past action

  • English: If I hadn’t let my anger get the better of me, I wouldn’t have ended up in this mess.
  • Spanish: Si no me hubiera dejado llevar por la rabia, no habría acabado en este lío.

📌 English: If I hadn’t let my anger… I wouldn’t have ended up… → If + past perfect, result in would have + past participle.
📌 Spanish: Si no me hubiera dejado… no habría acabado… → If + pluscuamperfecto de subjuntivo, result in condicional compuesto.

This is the third conditional: both the condition and result are in the past.


2.3. Modals + nuance

  • English: If you had told me, we could have fixed it before everything went to shit.
  • Spanish: Si me lo hubieras dicho, podríamos haberlo arreglado antes de que todo se fuera a la mierda.

📌 English modals (could have, might have, should have) add shades of meaning — possibility, ability, obligation.
📌 Spanish usually just uses podríamos haber, deberíamos haber, etc., without the same wide modal variety as English.


3. Probable Hypotheticals: When It Could Still Happen

  • English: If you talk to her now, she might forgive you.
  • Spanish: Si hablas con ella ahora, igual te perdona.

Both languages are now in the “this could actually happen” zone.

  • English: If + present simple → will/might/can + verb
  • Spanish: Indicative in the “si” clause → present/future in the result

⚠️ Notice: here Spanish often stays in indicative, not subjunctive, unless you’ve got trigger words like antes de que or para que.


3.1. Before and So That

  • English: Get the hell out before that bastard finds out and screws you over.
  • Spanish: Lárgate antes de que el cabrón se entere y te joda.
  • English: Study more so you don’t screw up the exam.
  • Spanish: Estudia más para que no te cagues en el examen.

👉 In these cases, English just keeps things simple (present tense). Spanish, however, jumps to subjunctive because the action hasn’t happened yet.


3.2. Future with a Bit of Drama

  • English: When you get back from your smoke, bring me a coffee.
  • Spanish: Cuando vuelvas de fumar, tráeme un café.

👉 English = when + present simple. Spanish = cuando + subjuntivo (if it’s future/uncertain).


4. Colloquial Expressions That Mirror the Logic

Sometimes we don’t even need an if/si for the same brain move.

  • English: I wish you’d stop bitching about it.
  • Spanish: Ojalá dejaras de dar la brasa con eso.
  • English: I wish voice notes had a legal time limit.
  • Spanish: Ojalá los audios de WhatsApp tuvieran límite legal de 30 segundos.

👉 Both languages use “alternate reality grammar” to express regret or wishful thinking.


4.1. Emotional Reactions and Judgy Comments

Spanish forces the subjunctive after emotions (me jode que, me alegra que, es una pena que).
English just uses “that” + present or past.

  • Spanish: Me jode que siempre llegues tarde.
  • English: It pisses me off that you’re always late.
  • Spanish: Es una pena que no puedas venir.
  • English: It’s a shame that you can’t come.

👉 Same meaning, but only Spanish marks it with a mood change.


5. Politeness and Softening the Blow

  • English: I would appreciate it if you stopped leaving your dirty socks on my bed.
  • Spanish: Te agradecería que dejaras de dejar tus putos calcetines sucios en mi cama.

5.1. The reality

  • English: I’d like a cold beer, please.
  • Spanish: Ponme una caña y que no me la pongas caliente, coño.

👉 Both languages use conditional/subjunctive to take the edge off. Though honestly, in Spain, people often just drop the politeness and go straight for the command.


6. Where the Parallel Breaks: What English Doesn’t Have (or Hides)

Here’s where things fall apart:

A. Subjunctive triggers that don't exist in English.

  • No creo que venga.I don’t think he’ll come.
  • Para que no se mosquee, no digas nada.So he doesn’t get pissed, don’t say anything.

B. Future clauses

  • Cuando termines, avísame.When you finish, let me know.
    👉 Spanish needs subjunctive (termines) for future/uncertain; English just sticks to present simple (finish).

C. Trigger words: aunque, quizá, tal vez

  • Aunque me pagues, no voy.
  • Aunque me pagues, no iría.
  • Even if you paid me, I wouldn’t go.
    👉 Spanish demands subjunctive for uncertainty. English doesn’t bother.

7. The Mindset Shift: One Mental Chip

Stop memorising endless tables. Instead, train your brain to ask:

  • Is this reality? → indicative (present/future).
  • Is this not reality? → subjunctive (Spanish) / conditional or “subjunctive fossil” (English).

That’s it. That’s the trick.


8. Mini Bilingual Practice

Fill in both versions:

  1. If I hadn’t stayed up so bloody late, ______.
    Si no me hubiera quedado hasta las tantas, ______.
  2. If you weren’t moaning all the bloody time, ______.
    Si no estuvieras quejándote todo el santo día, ______.
  3. Even if they offered me a million, ______.
    Aunque me ofrecieran un millón, ______.

👉 Key takeaway: If you can handle the subjunctive in Spanish, you already have the mental machinery for English conditionals — and vice versa. Different grammar, same brain.

If you liked this, you’ll love what’s coming.

If enough people show support, I’ll create a bilingual, culturally rich book for people who live between languages.

This is just a taste of a full bilingual project I’m building for people who don’t want to just learn a language—they want to live it.

Become a paid subscriber to support the project and get early chapters, behind-the-scenes updates, and downloadable resources.

We learn a language to communicate, and we communicate to connect.
So why would we market language like a social media scroll?
This project is human. Built on culture, not clickbait.
If you’re with me, let’s do it differently.
