To Be Replaced
To Be Substituted, To Be Switched
intransitive verb, godan verb
Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means replace, and this word means to be replaced, to be substituted, and to be switched.
This verb is intransitive, meaning it doesn't take a direct object. You'll sometimes see it with the particle を, though, because the を is showing a "path" rather than a direct object in this case.
The reading is the same as the one you learned with the kanji.
ドラえもんの声優が替わってから、観なくなってしまった。
I stopped watching Doraemon after the voice actor was replaced.
今回の選挙で政権が替わることになりました。
