Animal inverted stake, restrained by another (8)
I believe the answer is:
antelope
'animal' is the definition.
(I've seen this before)
'stake restrained by another' is the wordplay.
'stake' becomes 'ante' (anteing is a kind of staking).
'restrained by' becomes 'lop' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'another' becomes 'e' (I've seen this in other clues).
'ante'+'lop'+'e'='ANTELOPE'
'inverted' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for antelope that I've seen before include "Such as a gnu or eland" , "Springbok or gnu?" , "Hartebeest, perhaps" , "Hoofed beast" , "Fast runner" .)
