Crossword Genius

Illuminated about quantity (5)

Ross

I believe the answer is:

litre

'quantity' is the definition.
(litre is a kind of quantity)

'illuminated about' is the wordplay.
'illuminated' becomes 'lit' (synonyms).
'about' becomes 're' (regarding).
'lit'+'re'='LITRE'

(Other definitions for litre that I've seen before include "less than two pints" , "quantity of drink" , "It's equal to about 1.75 pints" , "Unit of liquid measure" , "Measure of liquid volume" .)

I've seen this clue in The Mirror.
