More anxious about the short bear (6)
I believe the answer is:
mother
'bear' is the definition.
(thesaurus)
'more anxious about the short' is the wordplay.
'more' becomes 'm'.
'anxious' becomes 'oer' (I can't explain this - if you can you should give a lot more credence to this answer).
'about' is an insertion indicator.
'short' means to remove the last letter.
'the' with its final letter removed is 'th'.
'oer' going around 'th' is 'other'.
'm'+'other'='MOTHER'
Can you help me to learn more?
(Other definitions for mother that I've seen before include "Be overprotective" , "Dam" , "Female parent" , "One who pours the tea?" , "Mum" .)
