Forming it

Addition今日は休講です。ちなみに、明日も休みです。

How to use it

Adds supplementary information on the SAME topic. The speaker already knew it beforehand, not something just remembered.

  • 「ちなみに」 = incidentally, by the way. B is directly related to A and is supplementary information: 「この店のラーメンはおいしい。ちなみに、餃子もおすすめだ」.
  • Different from 「ところで」 (a complete topic change) and 「そういえば」 (something just remembered): 「ちなみに」 is a prepared addition, usable in both writing and presentations.
  • Very common when presenting figures: 「売上は10%増えた。ちなみに、昨年は5%だった」.

Examples

  • There are no classes today. Incidentally, tomorrow is also off.

  • Sales grew 10% this term. For reference, last year the growth was 5%.

Keep in mind

  • B is on the same topic as A.
  • Also usable in written language.

Common mistakes

  • Wrong仕事(しごと)の話(はなし)は以上(いじょう)です。ちなみに、週末(しゅうまつ)は何(なに)をしますか。

    That's all for work talk. By the way, what are you doing this weekend?

    Correct仕事(しごと)の話(はなし)は以上(いじょう)です。ところで、週末(しゅうまつ)は何(なに)をしますか。

    For a complete topic change, use 「ところで」.

  • Wrongこの店(みせ)のラーメンはおいしい。ちなみに、明日(あした)も休(やす)みです。

    This shop's ramen is really good. Incidentally, tomorrow is also off.

    Correct今日(きょう)は休講(きゅうこう)です。ちなみに、明日(あした)も休(やす)みです。

    「ちなみに」 must add information related to the SAME topic already mentioned, not connect two unrelated things (good ramen and a day off).

Exam tips

  • 「ちなみに」 = adding more on the same topic; use 「ところで」 for a topic change.
