Why “recusal” is a great word
The formal withdrawal of a judge or official from a case due to a conflict of interest or bias, to preserve the integrity of a proceeding. From the verb 'recuse' (from Anglo-French *recuser*, from Latin *recusare* "to refuse, object to") + the noun-forming suffix '-al'. Unlike 'disqualification'—a broader, often externally imposed removal—or 'recusancy'—a principled refusal in matters of conscience—recusal is a precise, self-executed act of judicial abstinence. It is the empty chair at the bench, the council member leaving the chamber before a vote on a relative's bid, the gavel deliberately set aside so the light of judgment may fall upon another. It is the machinery of justice performing its coldest, most necessary virtue.
