grammarDetailPage.commonMistakes.wrong: この本ほんは何円なんえんっけ？

grammarDetailPage.commonMistakes.correct: この本ほんは何円なんえんだっけ？

grammarDetailPage.commonMistakes.why: After a noun or na-adjective, use だ (or だった) before っけ. Here 何円 is a noun phrase, so it requires だ.

grammarDetailPage.commonMistakes.wrong: 部長ぶちょう、会議かいぎは何時なんじだっけ？

grammarDetailPage.commonMistakes.correct: 部長ぶちょう、会議かいぎは何時なんじでしたっけ？

grammarDetailPage.commonMistakes.why: Plain-form っけ is too casual for a superior; use でしたっけ or switch to a polite question such as 何時なんじですか.

grammarDetailPage.commonMistakes.wrong: (To someone you just met) お名前なまえは何なんだっけ？

grammarDetailPage.commonMistakes.correct: お名前なまえは何なんですか。

grammarDetailPage.commonMistakes.why: っけ presupposes that you once knew the information. It sounds odd for something you are hearing for the first time.

Key points

Attach it to the plain form of the clause. Nouns and na-adjectives take だ (だっけ) or だった (だったっけ), as in 今日きょうは何曜日なんようびだっけ. It is only for things you knew or experienced before; for new information, use ですか or かな. With superiors, politer でしたっけ is possible, but it is still casual in tone. It can also express nostalgic recollection, as in 昔むかしはよく遊あそんだっけ。
