(This is a series on Phrasal Verbs. There are hundreds of phrasal verbs and many of them have no relation to the words that form them. When you are learning a new phrasal verb, I recommend learning it as a completely new piece of vocabulary, instead of trying to make sense of the two pieces of the word.)
Just like the last phrasal verb, bring up, today’s phrase has more than one meaning.
Examples
Turn off – Desligar
I forgot to turn off the television before I left for the day.
It is important to turn off the electricity before performing any maintenance.
Turn off – Repulsa
People who make a lot of noise when eating really turn me off.
Turn off can also be used as a noun.
Bloody movies are a turn off for me. I just don’t enjoy them.
