Awful bus lane disrupted around maximum traffic? (11)
I believe the answer is:
unspeakable
'awful' is the definition.
(I know that awful can be written as unspeakable)
'bus lane disrupted around maximum traffic?' is the wordplay.
I cannot quite understand how this works, but
'maximum' could be 'peak' (similar in meaning) and 'peak' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for unspeakable that I've seen before include "Is impossible pronunciation so" , "Was Marcel Marceau's act so" , "Too bad for words" , "dreadful" , "awful?" .)
