Notes: This is not a misspelling of squirrel, but it does sound similar
The word desuetude means “discontinuance from use or exercise; disuse”
This word goes back to the mid-1400s
Background / Notes
Though similar in meaning to “disuse”, the origin of desuetude is quite different. It comes from the Latin verb suecerre (to accustom). Our word is not as common as ‘disuse’.
