"The singer is unpopular."
Translation:가수는 인기가 없습니다.
the best and most unmarked form in real life : '그 가수는 인기가 없습니다.'
If used without the topic marker and only used with subject marker, There can be some subtle meaning variations.
"그 가수가 인기가 없습니다." : The (very) singer is unpopular. / It is the singer who is unpopular. / It is that the singer is unpopular.
Topic marker can be dropped, but with some pause.
"그 가수, 인기가 없습니다." : The singer, he is unpopular.
Every sentence with the singer is negative. I thought it was funny at first, but this reinforces a stigma that professional singers are boring and bad. This reinforces children to think Opera or classical singing is bad and has a very negative impact on my career, as I am a vocal performance graduate. If this is not fixed soon, I will stop recommending the app, leave a 1 star review, and send a letter to the company. Please change this.
