Explanation
いかんず is a classical, literary suffix meaning 'regardless of' or 'no matter what X is.' It is not used in modern everyday conversation and tends to appear in historical texts, formal speeches, or stylized writing. It emphasizes that the result or situation remains the same regardless of the condition described by the preceding element. Because it is archaic, it can sound solemn or old-fashioned in modern contexts and should be used deliberately for flavor or in translations of classical material.
天候いかんず、試合は行われる。
てんこういかんず、しあいはおこなわれる。

Regardless of the weather, the match will be held.

あいてのじつりょくいかんず、わたしたちはいどみつづける。
