Do combustible characters differ about a rattle? (14)
I believe the answer is:
discombobulate
'rattle?' is the definition.
(I've seen this before)
'do combustible characters differ about a' is the wordplay.
I cannot really understand how this works, but
'do' could be 'bob' (bobbing is a kind of doing) and 'bob' is located in the answer.
'about' could be 'c' (abbreviation for 'circa') and 'c' is present in the answer.
'a' is within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for discombobulate that I've seen before include "Upset" , "cause confusion" , "Confuse" , "Throw" , "rattle?" .)
