The correct phrase is "Ich habe den Fernseher eingeschaltet." The verb "einschalten" is a separable verb, and in the perfect tense, the prefix "ein" is separated from the main verb "schalten" and placed at the end of the sentence. Therefore, the correct past participle form is "eingeschaltet." **

The expression "den Wind aus den Segeln nehmen" is a German idiom that translates to "to take the wind out of someone's sails" in English.

The German phrase "Wer den Schaden hat, braucht für den Spott nicht zu sorgen" translates to "He who has the damage does not need to worry about the mockery." This proverb means that when someone has suffered a loss or is in a difficult situation, they do not need to also worry about being made fun of or ridiculed. It emphasizes the idea that it is unnecessary and unkind to mock or make fun of someone who is already dealing with a problem or hardship. **
