～っけ

About

～っけ is a casual sentence ender used to ask clarifying questions when the speaker can't quite remember a piece of information, is asking themselves a rhetorical question (about something that they can't remember), or is recollecting about something nostalgic.

～っけ can attach directly to a verb (or by using のだ・んだ), directly to an い-adjective, or to a noun/な-adjective using だ, だった, or でした.

E.g. この間あいだ行いった店みせの名前なまえは何なんだっけ？ "What was the name of the restaurant we went to the other day?"

E.g. 電気でんき消けしたっけ？ "Did I turn off the light?"

E.g. 学生がくせいの時とき、毎日まいにちここで食たべたっけ。 "I ate here every day when I was a student."

Nostalgic statements made using ～っけ are more casual than those made using ～ものだ.
