Substantial support for stars here? (5,4)
I believe the answer is:
great bear
'stars here?' is the definition.
'great bear' can be an answer for 'stars' (constellation Ursa Major). I am not sure about the 'here?' bit.
'substantial support' is the wordplay.
'substantial' becomes 'great' (I can't justify this - if you can you should give a lot more credence to this answer).
'support' becomes 'bear' (I've seen this before).
'great'+'bear'='GREAT BEAR'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for great bear that I've seen before include "Ursa Major" , "Major stars" , "Plough constellation" , "visible in the night sky" , "'Large ursine in the heavens (5,4)'" .)
