Air BBC car program in bits and pieces (4-1-4)
I believe the answer is:
bric-a-brac
'air' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'bbc car program in bits and pieces' is the wordplay.
I cannot really see how this works, but
an anagram of 'car' is 'rac' which is located in the answer.
'program' could be 'c' (C program is an example) and 'c' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for bric-a-brac that I've seen before include "Knick-knacks" , "Miscellaneous small ornaments" , "Old curiosities" , "Miscellaneous objects of little value" , "Motley collection" .)
