Assignmment given involved paper on a bird fallacy (15)
I believe the answer is:
misapprehension
'fallacy' is the definition.
'assignmment given involved paper on a bird' is the wordplay.
I cannot really see how this works, but
an anagram of 'paper' is 'appre' which is present in the answer.
'on' is within the answer.
'bird' could be 'hen' (hen is a kind of bird) and 'hen' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for misapprehension that I've seen before include "Mistaken belief" , "wrong understanding" , "False impression" .)
