ちなみにですが (by the way, but)

Grammar & Usage

fixed expression

neutral to polite

How it works

This phrase combines 'ちなみに' (by the way, incidentally) with 'ですが' (but, although it is). The 'ですが' softens the introduction, making it sound more polite or less abrupt than just 'ちなみに'. It serves to introduce a related, often supplementary or tangential piece of information.

Quick facts

nuance:While 'ちなみに' alone is fine, 'ちなみにですが' explicitly acknowledges the shift in topic with a polite 'but' (が), making the transition smoother and less intrusive.

politeness_level:The 'ですが' adds a layer of politeness and a gentle transition, making the phrase suitable for a range of formal to informal contexts without being overly stiff. It can also imply a slight hesitation or an awareness that the new information might be a digression.
