Debording

Meaning: going out of bounds; originally applied to bodies of water overflowing their banks or exceeding their boundaries. Also used to mean going to excess.

Usefulness: 1 (It's a fancy word for playing hooky: "Sorry I'm late; had some urgent debording to attend to.")

Logofascination: 2 (Related to border, unsurprisingly.)

In the wild: No, although it is giving me lexical deja vu; I'm sure I've read it somewhere outside Sir Thomas' works. As google shows, it had its peak use in the 18th and 19th centuries - it's also found in some Scottish dictionaries from that time.

Degrees: 1

Connections: n/a

Used in: The title of the unpublished epigram quoted in Monday's post, and in Sir Thomas' Ekskybalauron.  The Admirable Chrichton posts notices in the Sorbonne challenging its finest scholars to debate him all day about anything they please, and has such a lackadaisical preparation for this grilling that:

There arose upon him an aspersion of too great proness to such like debordings and youthful emancipations, which occasioned one less acquainted with himself then his reputation, to subjoin, some two weeks before the great day appointed, to that program of his, which was fixed on the Sorbone gate these words: “If you would meet with this monster of perfection, to make search for him, either in the taverne or bawdy-house, is the readyest way to finde him.”

Here I think Sir Thomas is alluding more to the French débordement, which carries connotations of debauchery as well as excess.
