An Eskimo has one, but two are normal (3)
I believe the answer is:
ski
'one but two are normal' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'an eskimo has' is the wordplay.
'has' indicates the answer is hidden within the clue.
'SKI' can be found hidden inside 'eskimo'.
Can you help me to learn more?
(Other definitions for ski that I've seen before include "Take part in a winter sport" , "Narrow runner built for travel in snow" , "Go on snow runners" , "Alpine runner" , "runner in winter" .)
