Sort of land found on the market (6)
I believe the answer is:
common
'sort of land' is the definition.
'common' can be an answer for 'land' (I've seen this before). I'm not sure about the 'sort of' bit.
'on the market' is the wordplay.
I cannot really see how this works, but
'on' is within the answer.
This explanation may well be incorrect...
'found' acts as a link.
Can you help me to learn more?
(Other definitions for common that I've seen before include "Widespread, prevalent" , "Ordinary or vulgar" , "Ten a penny" , "Occurring frequently, or ill-bred" , "Usual, of no particular distinction" .)
