A reliable test is to identify the job of the word before translating from English.
What each word does
abrir
to open
Use abrir for doors, windows, containers, files, and businesses.
ligar
to switch on
Use ligar for devices, lights, machines, and systems that begin operating.
How to choose
- abrir: Choose abrir if the sentence points to doors, windows, containers, files, and businesses.
- ligar: Choose ligar if the sentence points to devices, lights, machines, and systems that begin operating.
Examples
Abra a janela, por favor.
Open the window, please.
Ligue a luz, por favor.
Turn on the light, please.
Common trap
A device may use either verb with different meanings: abrir o computador is physically opening it; ligar o computador powers it on.
Practice it in context
Pick one sentence from your real life and write it twice: once with abrir, then once with ligar. If both versions feel possible, name the meaning shift.
