代わりに

代わりに is used to express substituting one thing for another. It emphasizes that one option is taking the place of another, often due to a choice, change, or compensation. It can imply a trade‑off: one thing is done or used in place of something else, or something is given as a substitute or replacement. Common contexts include: when someone fills in for another person, when paying or exchanging one thing for another, or when describing a different option used instead of the usual one. Note that the phrase attaches to the substitute item or action (the thing doing the substituting is the subject), and the thing being replaced is introduced by the particle の before 代わりに in noun phrases, or the verb form precedes 代わりに in verb phrases.
