Friend turns up with a pet - a pampered one (6)
I believe the answer is:
lapdog
'a pampered one' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'friend turns up with a pet' is the wordplay.
'friend' becomes 'pal' (pal can mean a friend).
'turns up' is a reversal indicator.
'with' means one lot of letters go next to another.
'a pet' becomes 'dog'.
'pal' in reverse letter order is 'lap'.
'lap'+'dog'='LAPDOG'
Can you help me to learn more?
(Other definitions for lapdog that I've seen before include "Submissive type" , "Devoted attendant" , "Small pampered pooch" , "little pet" , "Infatuated person - small docile pet" .)
