US shop one aims to relocate (4,7)
I believe the answer is:
homo sapiens
'us' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'shop one aims to relocate' is the wordplay.
'to relocate' indicates anagramming the letters (I've seen 'relocated' mean this).
'shop'+'one'+'aims'='shoponeaims'
'shoponeaims' with letters rearranged gives 'HOMO SAPIENS'.
Can you help me to learn more?
(Other definitions for homo sapiens that I've seen before include "The one existing species of Man" , "Human species" , "Modern humans" , "Relative of 1 across" .)
