What's Hornblower doing in the suburbs? (7)
I believe the answer is:
tooting
'doing in the suburbs?' is the definition.
Although both the answer and definition are present participle verbs, I cannot see how one could define the other.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for tooting that I've seen before include "London suburb" , "part of our capital" , "area south of Wandsworth" , "... what impatient motorist may be doing" , "South London area" .)
