All wrong like an avocado? (4-6)
I believe the answer is:
pear-shaped
'all wrong like an avocado?' is the definition.
The definition suggests an adjective which matches the answer.
'avocado?' is the wordplay.
I cannot really understand how this works, but
'avocado?' could be 'pear' (I've seen this before) and 'pear' is present in the answer.
The remaining letters 'shaped' 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 pear-shaped that I've seen before include "With hips very wide compared to the upper body" , "(Go) horribly wrong; like three Satie pieces" , "Bottom-heavy: (gone) wrong" , "Fat at one end and thin at the other - all wrong!" .)
