Mike and others argue about face of kroner that could be forged (9)
I believe the answer is:
metalwork
'mike and others argue about face of kroner that could be forged' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'mike and others argue about face of kroner' is the wordplay.
'mike' becomes 'M' (phonetic alphabet: alpha, bravo, charlie etc.).
'and others' becomes 'etal' (synonyms).
'argue' becomes 'row' (to row with someone is to argue with them).
'about' is a reversal indicator.
'face of' suggests taking the first letters.
The first letter of 'kroner' is 'k'.
'row' back-to-front is 'wor'.
'm'+'etal'+'wor'+'k'='METALWORK'
Can you help me to learn more?
(Other definitions for metalwork that I've seen before include "school subject, once" , "Creative manipulation of iron, tin etc" , "processing of gold maybe" , "Objects of gold, iron, copper etc" .)
