Quick answer
Deitar describes lying down or going to bed; dormir describes actually sleeping.
A reliable test is to identify the job of the word before translating from English.
What each word does
deitar
to lie down or go to bed
Use deitar for putting the body in a horizontal position.
dormir
to sleep
Use dormir for being in the state of sleep.
How to choose
- deitar: Choose deitar if the sentence points to putting the body in a horizontal position.
- dormir: Choose dormir if the sentence points to being in the state of sleep.
Examples
Vou me deitar cedo hoje.
I am going to bed early today.
Dormi oito horas.
I slept for eight hours.
Common trap
Going to bed does not guarantee sleep: eu me deitei às dez, mas só dormi à meia-noite.
Practice it in context
Pick one sentence from your real life and write it twice: once with deitar, then once with dormir. If both versions feel possible, name the meaning shift.
