Child, under six, framing current image (6)
I believe the answer is:
vision
'image' is the definition.
(thesaurus)
'child under six framing current' is the wordplay.
'child' becomes 'son' (son is a kind of child).
'under' is a charade indicator (letters next to each other).
'six' becomes 'VI' (Roman numerals).
'framing' indicates putting letters inside (inserted letters are framed by the outside letters).
'current' becomes 'I' (symbol for electric current).
'son' put after 'vi' is 'vison'.
'vison' going around 'i' is 'VISION'.
(Other definitions for vision that I've seen before include "Forward plan" , "Imagination" , "ideal?" , "Eyesight" , "Sight of an apparition?" .)
