Dog often turning up, interrupting my redesign (6)
I believe the answer is:
modify
'redesign' is the definition.
(thesaurus)
'dog often turning up interrupting my' is the wordplay.
'dog often' becomes 'fido' (I've seen this before. I am not sure about the 'often' bit.).
'turning up' shows that the letters should be reversed in order.
'interrupting' is an insertion indicator.
'fido' back-to-front is 'odif'.
'odif' put into 'my' is 'MODIFY'.
Can you help me to learn more?
(Other definitions for modify that I've seen before include "Adjust" , "reform" , "Revise" , "Adapt" , "Make partial changes to" .)
