Questions & Answers about jeoneun maeju sijangeseo gwaireul sayo.

Why is 저 followed by -는 (저는) here instead of -가 (제가)?

-는 is the topic marker, showing that 저 is what the sentence is about and framing a habitual statement. -가 is the subject marker, which puts more emphasis on the doer of the action. When you’re describing general routines, Koreans usually use 저는 rather than 제가.

What does 매주 mean and where should it go in the sentence?

매주 means every week and functions as a frequency adverb. Korean typically orders elements as time → place → object → verb, so starting with 매주 highlights the weekly habit:
매주 시장에서 과일을 사요.
You could also place it just before the verb, but leading with it is most natural.

Why do we use 시장에서 instead of 시장에 here?

The particle -에서 marks the location where an action takes place, so since you’re buying fruit at the market, you use 시장에서. -에 would mark a static location or the target of movement, not the site of an action like buying.

Why does 과일 take -을 (과일을)?

Direct objects in Korean take -을 if the noun ends in a consonant (and -를 if it ends in a vowel). 과일 ends with ㄹ, so you attach -을 to indicate that fruit is what you’re buying. Particles clarify each noun’s role even when context makes it clear.
