かわりにInstead of; in place of
かわりに introduces a person, thing, or action used in place of the one that would normally be chosen or expected.
What is being replaced?
Read the sentence as a two-part relationship: the part before かわりに identifies the normal or expected choice, and the rest of the sentence identifies the substitute. With a noun, remember that the noun before の is the item being replaced—not the replacement.
Things, people, and actions
Replacing one action with another
After a plain verb clause, the expression presents the following action as an alternative to the first. Both actions should be clear enough that the listener can understand what was not done and what was done instead.
直接会いに行くかわりに、詳しい手紙を書いた。
Instead of going to meet them in person, I wrote a detailed letter.
AnalyzeAn exchange between two actions
かわりに can also describe a reciprocal arrangement: one person does one task in exchange for another person doing a different task. This extends the same replacement idea, but the two sides should form an obvious exchange.
私が夕食を作るかわりに、弟が皿を洗う。
I will make dinner, and in return my younger brother will wash the dishes.
AnalyzeThis is an exchange of responsibilities rather than a simple choice between two methods.
Everyday substitution versus formal representation
かわりに is the broad everyday choice for substitution. に代わって is more formal and is especially natural when someone acts as an official representative or successor.
社長に代わって、副社長が式典で挨拶した。
The vice president gave the address at the ceremony on behalf of the president.
AnalyzeThe formal setting and representative role make the more formal expression natural here.
