Mythical primate shown up in photo of gibbon (7)
I believe the answer is:
bigfoot
'mythical primate' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'up in photo of gibbon' is the wordplay.
'up' says the letters should be written backwards (in down clue: letters go upwards).
'in' indicates the answer is hidden within the clue.
'toofgib' is hidden in the letters of 'photo of gibbon'.
'toofgib' back-to-front is 'BIGFOOT'.
'shown' acts as a link.
Can you help me to learn more?
(Other definitions for bigfoot that I've seen before include "Fabled hairy primate" , "Supposed ape of northwest US" , "Supposed American ape" , "Supposed NW US ape-like creature" , "American 'apeman'" .)
