Root Explanation
Conclusiveness → It is formed from "con-" (meaning together) and "cludere" (meaning to close). The word refers to the quality of bringing together evidence or arguments to close a matter definitively.
Memory Tip
Think of 'closing' a matter definitively when evidence comes 'together' — that's what conclusiveness means.
