The word "superintendent" is sometimes misspelled as "superintendant". In

looked in my custom dictionary, to confirm that neither version is included.
So why no flagging?

The OED gives "superintendant" as an obsolete spelling formerly used when
"superintendant" was considered a foreign loan word from French
("superintendant" is the still current French spelling).
