Meaning

Indicates that someone or something takes the place of another, expressing replacement or substitution. Equivalent to 'instead of,' 'in place of,' or 'on behalf of.'

This compound particle expresses that one person or thing substitutes for another. It has two main uses: acting on behalf of someone (representing them), and replacing something with a newer or different alternative. に代わって and に代わり are interchangeable, though に代わり is slightly more formal. The pre-nominal form に代わる is used before nouns. Unlike の代わりに, which is more casual and flexible, に代わって tends to imply a more formal or significant replacement and is frequently used in business, official, and news contexts.

Examples

1. 部長に代わって私が挨拶をします。 I will give the greeting in place of the department manager.
2. 手紙に代わってメールが主な連絡手段になった。 Email has become the main means of communication in place of letters.
3. 母に代わり父が学校の面談に来た。 My father came to the school conference instead of my mother.
