anecdotum

• anecdoton (Grecian)

Back-formation from anecdota, reinterpreting the nominative neuter plural case ending -a as a Latin case ending (singular: -um), rather than (as is etymologically-consistent) as an Ancient Greek case ending (singular: -on, from -ον (-on)); perhaps reinforced by Latin anecdotum.

From Ancient Greek ἀνέκδοτος (anékdotos, “accounts unpublished”), from ᾰ̓ν- (an-, “negative prefix”) (English an-) + ἔκδοτος (ékdotos, “published”), from ἐκδῐ́δωμῐ (ekdídōmi, “I publish”), from ἐκ (ek, “out”) +‎ δῐ́δωμῐ (dídōmi, “I give”).
