What does 다행이야 mean here, and why is it in this form?

다행이야 means That’s a relief or I’m glad to hear that.

It comes from 다행이다 = to be fortunate / to be a relief.

• 다행이다 is the dictionary form.
• 다행이야 is the casual spoken form.
• In a more polite style, you would say 다행이에요.

So this sentence is in casual speech, probably between family members, friends, or someone speaking informally.

Why is it 큰 염증 and not 크다 염증?

Because 크다 is the dictionary form of the adjective to be big. When a Korean adjective directly modifies a noun, it changes form.

• 크다 → 큰
• 큰 염증 = big/serious inflammation

This is like how English changes structure from is big to big before a noun:

• 염증이 크다 = the inflammation is big/severe
• 큰 염증 = big/severe inflammation

In this medical context, 큰 often means serious or major, not just physically large.
