TechnicalRegister
The loss of trademark protection that occurs when a brand name slides into use as the everyday label for the whole product category.
Once shoppers started calling every moving staircase an 'escalator,' the mark succumbed to genericide.
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.
