"Something came up" in Japanese


I always use this in English to excuse myself from a planned meeting/meet up
(professional or personal). Basically, I don't want to bother the interlocutor
with the details and notify them I am busy.

I am not happy with what I can currently produce:

  * 新しい予定があります
  * いけなくなりました

Could you suggest more natural ways and idiomatic ways to express the same
idea?




More natural expressions would include:

「ちょっと[用事]{ようじ}（or 用）ができてしまって。」

「[急]{きゅう}に[予定]{よてい}が[入]{はい}ってしまって。」

It would be nice to say 「すみません（が）」 or 「ごめんなさい」 at the beginning.

Informally, one could replace 「てしまって」 with 「ちゃって」. In business settings, I
recommend the former.

The ambiguous 「って/て」 ending is very common with these little expressions.
