💡 Grammar Points
The 'O' to 'UE' Change
The verb 'dormir' is irregular because the 'o' changes to 'ue' when stressed (like in 'duerme'). This happens for almost all forms except 'nosotros' and 'vosotros'.
Preterite Change
In the simple past (preterite), the 'o' changes to 'u' only for the 'él/ella/usted' and 'ellos/ellas/ustedes' forms (e.g., durmió, durmieron).
❌ Common Pitfalls
Forgetting the Stem Change
Mistake: "Él dorme en su cama."
Correction: Él duerme en su cama. Remember to change the 'o' to 'ue' in the present tense.
⭐ Usage Tips
Using 'Duerme' with Reflexive Pronouns
To emphasize falling asleep, Spanish uses 'dormirse'. If you say 'Se duerme', it means 'He/She is falling asleep' or 'He/She goes to sleep'.

When used as an informal command, 'Duerme!' means 'Sleep!'
duerme(verb)
Sleep!
?A direct command to 'tú' (you informal)
Go to sleep!
?Used for urgency
📝 In Action

A2It's already late, sleep now!
Duerme, mi amor, que mañana hay escuela.
A2Sleep, my love, because tomorrow is a school day.
💡 Grammar Points
Affirmative 'Tú' Command
The informal command form for 'tú' (you) is usually the same as the 'él/ella/usted' present tense form. So, 'duerme' means both 'he/she sleeps' and 'Sleep!'
⭐ Usage Tips
Negative Commands are Different
If you want to say 'Don't sleep!', you must use the subjunctive form: 'No duermas'.

Frequently Asked Questions
Why does 'duerme' have a 'ue' but 'dormimos' keeps the 'o'?
This is a common pattern in Spanish verbs! The 'o' changes to 'ue' only when that part of the word is strongly emphasized when you say it. For 'duerme,' the stress is on 'due-', but for 'dormimos,' the stress is on 'mi-', so the 'o' stays the same.
How do I say 'He slept' using the verb 'dormir'?
You need the simple past tense (preterite) form, which is 'durmió'. Notice the change from 'o' to 'u' in this past tense.
