Organisation for employment in fishing (7)
I believe the answer is:
network
'fishing' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'organisation for employment' is the wordplay.
'organisation for' becomes 'net' (I can't justify this - if you can you should give a lot more credence to this answer).
'employment' becomes 'work' ('work' can be a synonym of 'employment').
'net'+'work'='NETWORK'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for network that I've seen before include "System of roads, etc" , "(Eg, railway) system" , "Trek now (anag.)" , "Organisation" , "Chain of interconnected computers" .)
