What is the basic structure of this sentence?

It has two parts:

• 햇빛이 강하면 = if/when the sunlight is strong
• 선크림을 발라야 해요 = you have to apply sunscreen

So the pattern is:

• [condition] + [what you should/must do]

This is a very common Korean sentence structure.

Why does 햇빛 use 이?

이/가 marks the subject of the clause.

Here, 햇빛이 강하면 means if the sunlight is strong.
The thing that is strong is 햇빛, so it takes the subject marker 이.

• 햇빛 = sunlight
• 이 = subject marker
• 강하면 = if it is strong

So 햇빛이 means the sunlight as the subject.

What does 강하면 mean, and how is it formed?

강하면 comes from 강하다, which means to be strong/intense.

It is formed like this:

• 강하다 → stem 강하-
• 강하- + -면 → 강하면

-면 means if or when.

So 강하면 means:

• if it is strong
• when it is strong

In this sentence, it means the sunlight is intense/strong.
