Volume of tiler's work (5)
I believe the answer is:
litre
'volume' is the definition.
(I've seen this before)
'tiler's work' is the wordplay.
'work' indicates anagramming the letters.
'tiler' is an anagram of 'LITRE'.
'of' is the link.
(Other definitions for litre that I've seen before include "Nearly two pints" , "Measure of liquid volume" , "One thousand cubic centimetres" , "Fluid measure" , "less than two pints" .)
