Uncovered first ever yellow egret without a telescope (5,3)
I believe the answer is:
naked eye
'without a telescope' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'uncovered first ever yellow egret' is the wordplay.
'uncovered' becomes 'naked' (I've seen this before).
'first' says to take the initial letters.
The first letters of 'ever yellow egret' is 'eye'.
'naked'+'eye'='NAKED EYE'
Can you help me to learn more?
(Other definitions for naked eye that I've seen before include "It doesn't need a visual aid to see" , "(View) unaided by any optical instrument" , "With which to observe" , "Unaided vision" , "Observer" .)
