'epitaph' is the definition.
I know nothing about this answer so I can't tell whether this works.

'neat and precise form' is the wordplay.
'and' is a charade indicator (letters next to each other).
'form' is an anagram indicator (another form of the letters).
'neat'+'precise'='neatprecise'
'neatprecise' with letters rearranged gives 'REST IN PEACE'.

'of' acts as a link.
