Frame of roadhouse underpinned by aluminium and concrete (4)
I believe the answer is:
real
'concrete' is the definition.
(associated in meaning)
'frame of roadhouse underpinned by aluminium' is the wordplay.
I cannot really understand how this works, but
'aluminium' could be 'al' (Al is the chemical symbol for aluminium) and 'al' is located in the answer.
The remaining letters 're' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'and' acts as a link.
Can you help me to learn more?
(Other definitions for real that I've seen before include "Actual, existing" , "Actual; coin" , "Spanish football team" , "Genuine - old Spanish coin" , "Actual; Brazilian currency" .)
