〜がする
There's a smell / taste / sound / feeling of…machine translation
FormationNoun for a smell / taste / sound / sensation + が + する
〜がする is used when you perceive a smell, taste, sound, or sensation: においがする (there's a smell), 味がする (there's a taste), 音がする (there's a sound), 声がする (there's a voice), 気がする (have a feeling).
The thing perceived takes the particle が, and する here doesn't mean "to do" — the whole phrase means "to sense that there is…". To specify what the smell or taste is of, add a noun + の in front: カレーのにおいがする (there's a smell of curry), 変な味がする (it has a strange taste).
Compared with 聞こえる from the previous lesson: 音がする simply registers that "there's some sound", often with the source still unclear; 聞こえる emphasizes the sound carrying to your ears. The phrase 気がする ("have a feeling that…") will stay with you all the way up to N3, so get familiar with it now.
