Clumsily misused walkway crossing road (9)
I believe the answer is:
awkwardly
'clumsily' is the definition.
(thesaurus)
'misused walkway crossing road' is the wordplay.
'misused' is an anagram indicator.
'crossing' is an insertion indicator.
'road' becomes 'rd' (abbreviation).
'walkway' with letters rearranged gives 'awkwaly'.
'awkwaly' enclosing 'rd' is 'AWKWARDLY'.
(Other definitions for awkwardly that I've seen before include "Ungracefully" , "In a clumsy manner" , "Ineptly" , "In a clumsy way" , "In an ungainly way" .)
