After deduction, less than nineteen (3)
I believe the answer is:
net
'after deduction' is the definition.
The answer and definition can be both related to property as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'less than nineteen' is the wordplay.
'NET' is hidden within the letters.
But, I am uncertain how this is indicated.
Can you help me to learn more?
(Other definitions for net that I've seen before include "Final profit when all overheads have been deducted" , "Catch -- after all deductions" , "Butterfly trap" , "Meshed trap" , "Snare or trap" .)
