Sphere in which your fortune may lie (7,4)
I believe the answer is:
crystal ball
'in which your fortune may lie' is the definition.
The definition suggests a singular noun which matches the answer.
'sphere' is the wordplay.
I cannot quite see how this works, but
'sphere' could be 'ball' (ball is a kind of sphere) and 'ball' is found in the answer.
The remaining letters 'crystal' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for crystal ball that I've seen before include "Gaze here to see the future" , "Fortune-teller's essential equipment?" , "Fortuneteller's globe" , "see the result first in here?" , "Glass globe" .)
