Wonderful to tolerate constellation (5,4)
I believe the answer is:
great bear
'constellation' is the definition.
(Great Bear is an example)
'wonderful to tolerate' is the wordplay.
'wonderful' becomes 'great' (I've seen this before).
'to tolerate' becomes 'bear' (synonyms).
'great'+'bear'='GREAT BEAR'
(Other definitions for great bear that I've seen before include "'Large ursine in the heavens (5,4)'" , "Ursa Major" , "Large animal - same as 7" , "Major stars" , "Plough constellation" .)
