Concrete entry to motorway adjoined turf? (5)
I believe the answer is:
realm
'turf?' is the definition.
(I've seen this in another clue)
'concrete entry to motorway' is the wordplay.
'concrete' becomes 'real' (similar in meaning).
'entry' suggests taking the first letters (I've seen 'entry of' mean this).
The initial letter of 'motorway' is 'm'.
'real'+'m'='REALM'
'adjoined' is the link.
This may not be correct. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for realm that I've seen before include "Royal domain" , "Kingdom or sphere" , "where ruler holds sway?" , "Kingdom, domain" , "department" .)
