Where, with a friend, mum could have a holdiay (5)
I believe the answer is:
palma
'where' is the definition.
The definition suggests a singular noun which matches the answer.
'friend mum could have a holdiay' is the wordplay.
I cannot quite see how this works, but
'friend' could be 'pal' (pal can mean a friend) and 'pal' is found in the answer.
'mum' could be 'ma' (both can mean mother) and 'ma' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'with a' acts as a link.
Can you help me to learn more?
(Other definitions for palma that I've seen before include "Port on Majorca" , "Balearic capital and resort" , "Capital of Majorca" , "Capital of the Balearic Islands" , "tourist centre in the Med" .)
