Prestige owner somehow expecting this feature? (5,8)
I believe the answer is:
power steering
'this feature?' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'prestige owner somehow' is the wordplay.
'somehow' is an anagram indicator.
'prestige'+'owner'='prestigeowner'
'prestigeowner' with letters rearranged gives 'POWER STEERING'.
'expecting' acts as a link.
Can you help me to learn more?
(Other definitions for power steering that I've seen before include "Grit sweeper on? (anag) -- it makes driving easier" , "Driver's aid" , "help in driving" , "It gives strength to a driver's elbow" .)
