Questions & Answers about bajireul sagi jeone jumeoniga keunjido kkok hwaginhaeyo.

Why is it 바지를 and not just 바지?

Because 바지 is the object of 사다 (to buy), so it takes the object marker -를.

• 바지 = pants
• 바지를 사다 = to buy pants

Even though English often doesn’t mark objects, Korean usually does with particles.

What does 사기 전에 mean, and why is 사다 changed to 사기?

사기 전에 means before buying or before you buy.

Here, 사다 becomes 사기 because the verb is turned into a noun-like form with -기:

• 사다 = to buy
• 사기 = buying
• 사기 전에 = before buying

So the structure is:

• Verb stem + -기 전에 = before doing something

Examples:

• 먹기 전에 = before eating
• 자기 전에 = before sleeping

Could this also be 사기 전에는 or 사기 전? What is the difference?

Yes.

• 사기 전 = before buying
• 사기 전에 = before buying / before you buy
• 사기 전에는 = before buying, as for that time / at least before buying

In this sentence, 사기 전에 is the most neutral and natural choice.

The extra -는 in 전에는 adds contrast or emphasis, something like:

• At least before buying, check...
