Excited Italian has a go at it wrongly (7)
I believe the answer is:
agitato
'excited italian' is the definition.
'agitato' can be an answer for 'excited' (I've seen this before). I am not sure about the 'italian' bit.
'a go at it wrongly' is the wordplay.
'wrongly' is an anagram indicator.
'go'+'at'+'it'='goatit'
'goatit' is an anagram of 'gitato'.
'a'+'gitato'='AGITATO'
'has' acts as a link.
Can you help me to learn more?
(Other definitions for agitato that I've seen before include "in troubled way" , "stirring music" , "frenetically scored" , "Musical indication; a go at it (anagram)" , "In restless musical style" .)
