Half chance of landing in a spin (5)
I believe the answer is:
tails
'half chance of landing' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'a spin' is the wordplay.
I cannot really see how this works, but
'a' is present in the answer.
The remaining letters 'tils' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for tails that I've seen before include "as opposed to heads" , "Ends" , "Follows closely" , "the back of bears - bulls too" , "Animals' extremities" .)
