事こと新あたらしく

adverb

anew; again; specially; formally

Used when something is done again from scratch, with special care, or in a formal manner. Often implies a deliberate, fresh start rather than a simple repetition. The 'specially' and 'formally' nuances are less common and context-dependent.

• 事こと新あたらしく説せつ明めいするまでもない。

  There's no need to explain it all over again.

• 彼かれは事こと新あたらしくその問もん題だいを取とり上あげた。

  He brought up the issue anew, as if it were something special.
