Loud, disorderly line diplomatically eviscerated (5)
I believe the answer is:
rowdy
'loud' is the definition.
(thesaurus)
'disorderly line diplomatically eviscerated' is the wordplay.
'disorderly line' becomes 'row' (a row or line of things. I am not sure about the 'disorderly' bit.).
'eviscerated' means to remove the middle letters (the word is disembowelled of its inside letters).
'diplomatically' with its centre taken out is 'dy'.
'row'+'dy'='ROWDY'
Can you help me to learn more?
(Other definitions for rowdy that I've seen before include "Uproarious" , "yob" , "Loud and disorderly" , "Raucous" , "Noisy and unruly" .)
