Annoyed at dirtier manoeuvre (9)
I believe the answer is:
irritated
'annoyed' is the definition.
(I know that annoyed can be written as irritated)
'at dirtier manoeuvre' is the wordplay.
'manoeuvre' is an anagram indicator.
'at'+'dirtier'='atdirtier'
'atdirtier' with letters rearranged gives 'IRRITATED'.
(Other definitions for irritated that I've seen before include "Annoyed" , "Cross" , "Irked" , "rubbed up the wrong way" , "put out" .)
