Questions & Answers about hoesa-eseo piryohan jangbireul sasseoyo.

Why do we use 회사에서 instead of 회사에 in this sentence?

In Korean particles:

• -에 marks a static location (“at/to”).
• -에서 marks where an action takes place.
  Here you’re talking about the place where you bought something, so you need 회사에서 (“at the company”) rather than 회사에.

What does 필요한 mean, and why is it placed before 장비?

필요하다 means “to be necessary.” To turn it into a modifier for a noun (an attributive form), you:

1. Drop -다 → 필요하
2. Attach -ㄴ (since the stem ends in a vowel) → 필요한
   So 필요한 장비 literally means “equipment that is necessary.”

Why is 장비 followed by -를 (as in 장비를)?

-를 is the object particle used after a noun ending in a vowel. It marks 장비 as the direct object of 샀어요 (“bought”). If the noun ended in a consonant, you would use -을 instead.

What is the nuance or politeness level of 샀어요?
