knowledge qualifier
C2CEFR level
92/100Rarity: very rare
TechnicalRegister
A limiting phrase confining a warranty to matters within the giver's actual or constructive awareness.
They larded every rep with a knowledge qualifier, so unless we could prove the CFO knew, the warranty simply did not bite.
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.
