💡 Grammar Points
The 'Y' Irregularity
The verb 'oír' is special! When the vowel 'i' of the ending comes immediately after the vowel 'o' in the stem, the 'i' changes to a 'y' to make the sound smoother, as seen in 'oyó' and 'oyeran'.
Action Completed in the Past
'Oyó' uses the preterite tense, which means the act of hearing started and finished at a specific time in the past (e.g., 'He heard it right then').
❌ Common Pitfalls
Hearing vs. Listening
Mistake: "Using 'oyó' when you mean 'paid attention' (Escuchó la conferencia)."
Correction: Use 'oyó' for perceiving sound (like an unexpected noise) and 'escuchó' for actively paying attention (like listening to music or a lecture).
⭐ Usage Tips
Focus on the Third Person
'Oyó' is only used for singular subjects: 'él' (he), 'ella' (she), 'usted' (formal you), or 'eso' (it/that).

Frequently Asked Questions
Why does 'oír' change the 'i' to a 'y' in 'oyó'?
This is a key irregularity! When the vowel 'i' is between two other vowels (like 'o-i-ó'), Spanish grammar changes the 'i' to a 'y' to prevent an awkward sound and to separate the two vowel sounds clearly. This happens in the preterite and the subjunctive tenses.
