Globe, say, or Earth spinning in telescope's frame (7)
I believe the answer is:
theatre
'globe say' is the definition.
(Shakespeare's Globe is an example)
'earth spinning in telescope's frame' is the wordplay.
'spinning' is an anagram indicator.
'in' is an insertion indicator.
'frame' says to hollow out the word (remove centre letters).
'telescope' with its middle removed is 'te'.
'earth' is an anagram of 'heatr'.
'heatr' going into 'te' is 'THEATRE'.
'or' acts as a link.
(Other definitions for theatre that I've seen before include "The rate (anag.)" , "Room for surgery" , "Where you might find ham" , "Show" , "eg The Globe" .)
