Questions & Answers about soni geonjohal ttaeneun rosyeoneul jogeum bareumyeon johayo.
손이 uses the subject marker 이, because 손 is the thing being described as dry.
- 손이 건조하다 = the hands are dry
- Here, 건조하다 describes the condition of the hands, so 손 is the grammatical subject.
If you said 손은, it would sound more like you were setting up hands as a topic, possibly with contrast, such as As for the hands, they’re dry.
In this sentence, 손이 is the most natural choice.
건조할 때 means when [the hands] are dry.
Then 는 is added to 때:
- 건조할 때 = when they are dry
- 건조할 때는 = when they are dry, as for that situation / in that case
This 는 gives a slight sense of topic or contrast. It often appears in advice sentences like this:
- 아플 때는 쉬세요. = When you’re sick, rest.
- 추울 때는 따뜻하게 입으세요. = When it’s cold, dress warmly.
So here, 때는 helps frame the sentence as general advice for that situation.
