Friend with mother in tourist centre (5)
I believe the answer is:
palma
'tourist centre' is the definition.
The definition suggests a singular noun which matches the answer.
'friend with mother' is the wordplay.
'friend' becomes 'pal' (pal can mean a friend).
'with' means one lot of letters go next to another.
'mother' becomes 'ma' (ma can mean mother).
'pal'+'ma'='PALMA'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for palma that I've seen before include "Capital of Majorca" , "Capital of the Balearic Islands" , "Balearic capital and resort" , "Town on Majorca" , "Port on Majorca" .)
