As at the outset with development in egg? (6)
I believe the answer is:
ageing
'as at the outset with development in egg?' is the definition.
I can't tell whether this defines the answer.
'as at the outset with development in egg?' is the wordplay.
'at the outset' indicates taking the first letters.
'with' is a charade indicator (letters next to each other).
'development' indicates anagramming the letters.
The first letter of 'as' is 'a'.
'in'+'egg'='inegg'
'inegg' with letters rearranged gives 'geing'.
'a'+'geing'='AGEING'
Can you help me to learn more?
(Other definitions for ageing that I've seen before include "no longer fresh" , "rather old" , "Growing older" , "Elderly" , "process of development" .)
