True about space for dish (6)
I believe the answer is:
tureen
'for dish' is the definition.
(tureen is a kind of dish)
'true about space' is the wordplay.
'about' is an anagram indicator.
'space' becomes 'en' (in printing, a space as wide as a letter 'n').
'true' with letters rearranged gives 'ture'.
'ture'+'en'='TUREEN'
(Other definitions for tureen that I've seen before include "A deep covered dish for serving soup" , "Large, deep serving dish with a cover" , "Soup container" , "Soup-dish" , "Holder of first course" .)
