House with no stove (6)
I believe the answer is:
orange
'house' is the definition.
(Dutch royal house, as in William of Orange)
'with no stove' is the wordplay.
'with' means one lot of letters go next to another.
'no' becomes 'O' (O resembles 0).
'stove' becomes 'range' (synonyms).
'o'+'range' is 'ORANGE'.
(Other definitions for orange that I've seen before include "Between red and yellow on the spectrum" , "Go earn the fruit" , "A rainbow colour" , "Princely house" , "Unrhymable word?" .)
