- The word 勉強 is also used in shopping to describe a discount or a price reduction, which is literally asking the seller to 'study' the price to make it lower.
- Historically, the term 勉強 did not refer to schoolwork but described the act of 'forcing' or 'striving' oneself through a difficult hardship.
- In Japanese, it is common to omit the word 'I' entirely in this phrase. Because the speaker is expressing a personal feeling of obligation, the subject is understood through context without ever needing to say 'watashi' (I).
