Wild lamenting - what a row! (9)
I believe the answer is:
alignment
'a row' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'wild lamenting' is the wordplay.
'wild' is an anagram indicator.
'lamenting' anagrammed gives 'ALIGNMENT'.
'what' acts as a link.
Can you help me to learn more?
(Other definitions for alignment that I've seen before include "Alliance" , "Arrangement in a straight line" , "Act of straightening" , "political position" , "Dressing" .)
