noun
calling back; return phone call
Slang noun used in casual contexts, often among younger speakers or in text messages, to refer to a return call or the act of calling someone back.
さっきの着信、折電しとくね。
I'll call back about that missed call just now.
折電ありがとう。
Thanks for calling back.
Standard, formal term for a return phone call, unlike the slangy 折電.
Loanword from English, also used for callback, but 折電 is more casual and abbreviated.
Abbreviation of 折り返し電話 (おりかえしでんわ, 'return call'), combining 折 (おり, 'fold' or 'turn back') and 電 (でん, 'telephone').
