～こととて

When to use

Formal, literary; specifically apologizes for or excuses an outcome as unavoidable given the circumstances - politely deflects blame, distinct from がゆえに's more neutral logical framing.

Explanation

The ～こととて grammar point expresses a reason or premise in a slightly formal or literary way. It can often be interpreted as 'since' or 'because'.
