"수요일마다 저는 한국어를 공부해요."
Translation:Every Wednesday I study Korean.
I study Korean everyday from 0 for the past like 5 month even thought I only do 1 lesson per day and take like 1 hour on it (I'm stupid and gotta take notes and repeat the sentence over and over ok? don't judge, just want to actually get good )(nah the truth is I spend half of the time in the comment section )
Yes, "I study Korean on Wednesdays" or "I study Korean every Wednesday" or "I study Korean on Wednesday" are all ways a native English speaker could answer the question, when do you study Korean? "I study Korean on Wednesday" might be used when discussing your study schedule. Although the day is singular it is understood you mean every Wednesday. However, if asked the question, they would likely drop most of the sentence and answer something like "Every Wednesday".
