The state of being no longer used or practiced; disuse through neglect. A condition where something falls into obsolescence from lack of use.
From Latin 'desuetudo,' from 'desuetus' (disaccustomed), combining 'de' (away from) and 'suetus' (accustomed). The word entered English in the 14th century through legal terminology.
Think 'disused attitude' - desuetude happens when society's attitude toward something changes and it falls into disuse. Like old laws that nobody follows anymore!
