mootness
C2CEFR level
85/100Rarity: very rare
TechnicalRegister
The condition of a dispute that has ceased to present a live controversy, depriving the court of a reason to decide it.
The detainee's release raised a question of mootness, though the court heard the appeal on a point of general importance.
Rarity runs from 0 (a word everyone knows) to 100 (almost never seen outside specialist or literary writing). Level is the word's real difficulty on the CEFR scale, from A1 to C2.
