Questions & Answers about i yageun yakhyoga ppallaseo dahaengiya.

What does 약효 mean here, and how is it different from 약?

약 means medicine or drug.

약효 means the medicinal effect, the effect of the medicine, or how well the medicine works.

So in this sentence:

• 이 약은 = as for this medicine
• 약효가 빠르다 = its effect is fast / it works quickly

Korean often uses a separate word like 약효 when talking specifically about the medicine’s effect, not just the medicine itself as an object.

Why does the sentence use both 이 약은 and 약효가? Isn’t that repetitive?

It can feel repetitive in English, but it is natural in Korean.

The structure is:

• 이 약은 = as for this medicine
• 약효가 빠르다 = the effect is fast

So the sentence is organized like this:

• Topic: this medicine
• Subject of the description: its effect

A very literal breakdown would be:

• As for this medicine, its effect is fast, so that’s a relief.

Korean often introduces a broad topic first, then gives a more specific subject inside that topic.
