English Grammar · Level C1 · CLIL: Spain

When Gaudí lay in a Barcelona hospital in June 1926, after being struck by a tram, his greatest masterpiece was still unfinished. If only he had lived to see it complete. That single sentence unlocks one of the most nuanced — and most satisfying — structures in advanced English: wish and if only.

What do ‘wish’ and ‘if only’ actually do?

Both expressions describe an imaginary world that is different from reality — something we want but don’t have, or something that happened (or didn’t happen) that we would change if we could. At C1 level, the key is knowing which tense follows “wish” or “if only”, because it signals exactly what kind of unreality you mean.

The core insight: after “wish” and “if only”, the tense steps back one step from reality. Present wish → past simple. Past regret → past perfect. Desire for change now → would + infinitive.

“If only” carries slightly more emotional weight than “wish” — it tends to appear when the feeling is intense: deep regret, frustration, longing. In everyday conversation you’ll hear both; in literary or formal writing, “if only” is the more dramatic choice.

The three C1 structures

Structure Form Meaning Example from Spain
Present wish / imaginary now wish/if only + past simple The situation is different from reality right now (or in future) I wish I lived in Seville. (but I don’t)
Past regret wish/if only + past perfect We regret something that happened (or didn’t happen) in the past If only Gaudí had seen the Sagrada Família completed.
Frustration / desire for change wish/if only + subject + would + base verb We want someone (or something) to stop/start doing something; we can’t use ‘would’ for our own actions I wish tourists would learn a few words of Catalan.

An important nuance: wish + could

When the wish is about ability — something you can or cannot do — use could rather than “would” or “was able to”.

  • I wish I could dance flamenco like that. ✓
  • I wish I was able to dance flamenco. (grammatically possible but less natural)
  • I wish I would dance flamenco. ✗ (wrong — “would” for your own actions is not used with “wish”)

‘Were’ or ‘was’ after wish / if only?

Formally, the subjunctive form were is used for all persons: “I wish I were in Barcelona right now.” In informal speech, was is increasingly common and is widely accepted. At C1 level, you should know both — and use were in writing and formal contexts.

Quick test: Can you replace “wish” with a conditional clause? If yes, you have the right structure.
“I wish I lived in Seville” → “If I lived in Seville, I would be happy.” ✓ (both use hypothetical past simple)

Spain, seen through ‘wish’ and ‘if only’

Spain offers a rich backdrop for these structures because its history and culture are full of things worth longing for, lamenting, and celebrating.

The Sagrada Família: a 144-year dream realised

Antoni Gaudí began work on his masterpiece in Barcelona in 1882. He dedicated the last fifteen years of his life entirely to the Sagrada Família, even living on site during his final months. Then, on 7 June 1926, he was struck by a tram crossing the street. Three days later, he died — at 73, without ever seeing it finished. His body now rests in the crypt of the very building he gave his life to build.

In February 2026, the central Tower of Jesus Christ was completed, rising to 172.5 metres — making it the world’s tallest church. On 10 June 2026, exactly one hundred years after Gaudí’s death, Pope Leo XIV blessed the completed tower in Barcelona.

Gaudí’s story is almost made for these grammar structures:

  • If only Gaudí had lived to see the central tower completed in 2026. (past regret)
  • He wished he could witness every stone being placed. (desired ability, reported)
  • I wish the building hadn’t taken 144 years to finish. (past regret)

Flamenco: the art of longing

Flamenco emerged in 15th-century Andalusia as an expression of joy, grief, and passion — all the emotions that “wish” and “if only” carry. In 2010, UNESCO recognised flamenco as a Masterpiece of the Oral and Intangible Heritage of Humanity. Spain as a whole counts more than 45 UNESCO World Heritage Sites, from the Alhambra to Gaudí’s works in Barcelona.

  • I wish I understood the lyrics of flamenco songs — the emotion is so raw. (present wish)
  • If only the concert hadn’t ended so soon. (past regret)
  • I wish the flamenco festival would come to our city. (desire for change)

Olive oil: the liquid gold of Andalusia

Spain is the world’s largest producer of olive oil, responsible for roughly 40% of global production — twice as much as Italy. More than 350 million olive trees grow across the landscape, most of them concentrated in the province of Jaén in Andalusia. The country exports to over 160 countries, making olive oil one of Spain’s most prized gifts to the world.

  • I wish I had an olive grove in Jaén — imagine the harvest every autumn. (present wish)
  • If only our local supermarket would stock better Spanish olive oil. (frustration, desire for change)

La Tomatina: a wish come true (and then ticketed)

Every last Wednesday of August, the small town of Buñol in Valencia hosts La Tomatina — the world’s biggest food fight. Around 100–150 tonnes of overripe tomatoes are hurled through the streets in a single hour. Until 2013, anyone could simply show up; after crowds became unmanageable for a town of just 9,000 people, the event was capped at 20,000 ticketed participants.

  • I wish I had gone before it became ticketed — it must have been wonderfully chaotic. (past regret)
  • If only we had bought our tickets earlier; they sold out in hours. (past regret)
  • I wish the organisers would increase the capacity slightly. (desire for change)

Common mistakes for Spanish speakers

Five traps to avoid

1. Using the present tense instead of past simple after ‘wish’
Spanish speakers sometimes carry the logic of ojalá + present subjunctive (“ojalá pueda ir”) into English and forget the back-shift.

✗ I wish I can visit the Alhambra this year.
✓ I wish I could visit the Alhambra this year.
Remember: present wishes → past tense form. ‘Can’ back-shifts to ‘could’.

2. Using ‘wish + would’ for your own actions
‘Would’ after ‘wish’ signals frustration about someone else’s behaviour, or an external situation you want to change. You cannot use “I wish I would…” for your own desires or plans.

✗ I wish I would go to Barcelona next summer.
✓ I wish I could go to Barcelona next summer. (ability / opportunity)
✓ I wish I were going to Barcelona next summer. (imaginary future plan)

3. Using past simple for past regrets (instead of past perfect)
When we regret something that already happened, the tense must step back to past perfect — not simple past.

✗ I wish I didn’t miss La Tomatina last summer.
✓ I wish I hadn’t missed La Tomatina last summer.
The event is finished and in the past → past perfect (‘hadn’t missed’).

4. Using ‘if only + would’ for your own actions
The same rule applies when using ‘if only’: the ‘would’ structure requires a different subject causing the frustration.

✗ If only I would study Spanish grammar every day.
✓ If only I studied Spanish grammar every day. (present wish about yourself)

5. Confusing ‘I wish you luck’ (fixed phrase) with the grammar structure
“I wish you luck / well / a safe journey” is a fixed social expression — it does not follow the back-shift rule. Spanish speakers sometimes apply the grammar rules here unnecessarily.

✗ I wish you would have a safe journey. (applying the grammar structure)
✓ I wish you a safe journey. (fixed expression — noun phrase, no back-shift needed)
✓ I hope you have a safe journey. (natural alternative)
