Joy of journalist lifted by something illuminating (7)
I believe the answer is:
delight
'joy' is the definition.
(I know that joy can be written as delight)
'journalist lifted by something illuminating' is the wordplay.
'journalist' becomes 'ed' (short for editor).
'lifted' is a reversal indicator (going up in down clue).
'by' says to put letters next to each other.
'something illuminating' becomes 'light' (a light illuminates one's way).
'ed' backwards is 'de'.
'de'+'light'='DELIGHT'
'of' is the link.
(Other definitions for delight that I've seen before include "Enchant" , "See 5" , "Give great pleasure to" , "Captivate" , "Greatly please" .)
