Freehold title that's amongst the least ratable (6)
I believe the answer is:
strata
'freehold title that's' is the definition.
I can't tell whether this definition defines the answer.
'amongst the least ratable' is the wordplay.
'amongst' says the answer is hidden in the clue.
'STRATA' is hidden within 'least ratable'.
Can you help me to learn more?
(Other definitions for strata that I've seen before include "Geological layers" , "Layers of rock on earth's surface" , "Levels, grades or social classes" , "Tiers of thicknesses" , "hard beds" .)
