Questions & Answers about sajeoneul yeoreoyo.

What is the implied subject in 사전을 열어요?

Korean often omits the subject when it’s obvious from context. In 사전을 열어요, the implicit subject is usually I (“I open the dictionary.”). If you use it as a polite request, the implied subject can be you (“Please open the dictionary.”), but grammatically the same form applies.

Why is there -을 attached to 사전 (making 사전을)? What does it indicate?

-을 is the object-marking particle used after a consonant. It marks 사전 (“dictionary”) as the direct object of the verb. If a noun ends in a vowel, you would use -를 instead.

What is the dictionary form of 열어요, and how is it conjugated into the polite present tense?

The base (dictionary) form is 열다 (“to open”). Conjugation steps:

1. Remove -다 → 열 (stem)
2. Add -어요 (polite present ending) → 열어요

Why do we use -어요 rather than -아요 when conjugating 열다?
