Zoo resident phoned in published article (5-4)
I believe the answer is:
orang-utan
'zoo resident' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'phoned in published article' is the wordplay.
'phoned' becomes 'rang' ('ring' can be a synonym of 'phone').
'in' means one lot of letters goes inside another.
'published' becomes 'out' (a published book is 'out').
'article' becomes 'an' (English indefinite article).
'rang' inserted inside 'out' is 'orangut'.
'orangut'+'an'='ORANG-UTAN'
Can you help me to learn more?
(Other definitions for orang-utan that I've seen before include "Anthropoid mammal of Indonesia" , "Endangered ape" , "Angora nut for long-armed ape of Burma" , "Species of ape" , "Endangered primate" .)
