One-sided favouritism, as in bowls (4)
I believe the answer is:
bias
'one-sided favouritism' is the definition.
'bias' can be an answer for 'favouritism' (I've seen this before). I'm not sure about the 'one-sided' bit.
'as in bowls' is the wordplay.
I cannot quite see how this works, but
'as' is found in the answer.
The remaining letters 'bi' 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).
Can you help me to learn more?
(Other definitions for bias that I've seen before include "Inclination of prejudice" , "An influence against, prejudice" , "Prejudice, one-sidedness" , "(Bowls) irregular shape" , "A leaning or prejudice" .)
