What do the particles 부터 and 까지 indicate in 화요일부터 금요일까지 and 오전 9시부터 오후 3시까지?
부터 means from, and 까지 means until or up to. They mark the beginning and end of a range. In this sentence there are two ranges: days of the week and hours of the day.
Why do we specify 오전 9시 and 오후 3시 rather than just 9시부터 3시까지?
Korean typically uses a 12-hour clock, so 오전 (morning) and 오후 (afternoon) clarify whether it’s before or after noon.
What does 그 건물에서 mean, and why is the particle 에서 used here?
그 건물에서 means at that building. The particle 에서 marks where the action (working) takes place.
Why is the verb 일해요, and what does the ending -아요 signify?
The dictionary form is 일하다; 일해요 is its polite present tense form. The ending -아요 attaches because the verb stem 일하 contains the vowel ㅏ.
I don’t see a subject like 저는 or 나는. Is something missing?
Korean often omits the subject when it’s clear from context. Here, you can assume the speaker means I.
Why does 화요일부터 금요일까지 (days) come before 오전 9시부터 오후 3시까지 (hours)? Is it possible to switch them?
Korean orders time expressions from larger units to smaller (year → month → day → hour → minute). That’s why the day range comes before the hour range. You could switch them, but this sequence sounds more natural.
Do we need commas in this sentence?
Commas in Korean are optional. You might see 화요일부터 금요일까지, 오전 9시부터 오후 3시까지 그 건물에서 일해요, but it reads perfectly well without them.
