Opening post first female's left for scripture class (7)
I believe the answer is:
orifice
'opening' is the definition.
('orifice' can be a synonym of 'opening')
'post first female's left for scripture class' is the wordplay.
I cannot quite understand how this works, but
'first' could be 'i' (I in Roman numerals eg Elizabeth I) and 'i' is found in the answer.
an anagram of 'for' is 'orf' which is present in the left over letters.
The remaining letters 'ice' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for orifice that I've seen before include "8 [OPENING]" , "For CIE, I look for an opening" , "provided by gold and diamonds" , "Hole, opening" , "Aperture" .)
