obelize
To mark (a written or printed passage) with an obelus; to judge as spurious or doubtful.
All modern classicists like to display due caution before coming to a conclusion and will reluctantly obelise any words in a manuscript that resist obvious emendation before deciding that on balance one version is better than another.
Where it comes from
From Hellenic Ancient Greek ὀβελίζειν (obelízein), from ὀβελός (obelós, “obelus”).
