Recognises a definition failing the substitution test

What it means

Replacing the term with its definition in a normal sentence changes or breaks the meaning.

How it is assessed

Flags the deficient case and passes the acceptable one. Deficient: arrears rate: loans that are overdue. "The arrears rate rose to 3 %" becomes "The loans that are overdue rose to 3 %" Acceptable: arrears rate: proportion of loans whose arrears day count is above zero at the end of a given period. "The proportion of loans whose ... rose to 3 %" still reads correctly
