Missing organs primarily entertaining the old? Not so (7)
I believe the answer is:
eyeless
'missing organs primarily entertaining the old? not so' is the definition.
I can't tell whether this defines the answer.
'primarily entertaining the old? not so' is the wordplay.
'primarily' says to take the initial letters.
'the old?' becomes 'ye' (resembles a historical spelling of 'the').
'not so' becomes 'less' (eg 'not so big' means 'less big').
The initial letter of 'entertaining' is 'e'.
'e'+'ye'+'less'='EYELESS'
Can you help me to learn more?
(Other definitions for eyeless that I've seen before include "Blind" , "how needle may be defective" , "Like Samson in Gaza" , "unsighted?" , "Without the means to see" .)
