💡 Grammar Points
Irregular Past Tense
The verb 'caer' is irregular in the simple past tense (preterite). Notice the 'y' instead of an 'i' in 'cayó' and 'cayeron'. This sound change makes the pronunciation smoother.
❌ Common Pitfalls
Using 'Se' vs. Not Using 'Se'
Mistake: "La mesa cayó (The table fell, like a kingdom collapsed)."
Correction: La mesa se cayó (The table fell down, physically). Use 'se' before 'caer' for accidental, physical falls.
⭐ Usage Tips
Accidental Events (The Se Rule)
When someone or something accidentally falls, we almost always use 'se' before the verb (like 'se cayó'). This construction emphasizes that it was an unintended event.

Frequently Asked Questions
Why does 'caer' suddenly have a 'y' (cayó) in the past tense?
This is a common irregularity in Spanish verbs ending in a vowel + 'er' or 'ir'. When the 'i' of the simple past ending tries to squeeze between two other vowels (e.g., *ca-i-o*), Spanish rules turn that weak 'i' into a stronger 'y' sound ('cayó') for better pronunciation.
How do I know if 'cayó' means 'fell' or 'was defeated'?
Context is key! If it's about a person or small object, it's usually a physical fall (like a ball). If it's about a government, empire, or company, it usually means it collapsed or failed.
