Name one child after an inventor (6)
I believe the answer is:
edison
'inventor' is the definition.
(I know that Edison is a inventor)
'name one child after an' is the wordplay.
'name' becomes 'ed' (short for Edward).
'one child' becomes 'son' (son is a kind of child).
'after' is a charade indicator (letters next to each other).
'an' becomes 'i' (Roman numeral for one).
'son' put after 'i' is 'ison'.
'ed'+'ison'='EDISON'
(Other definitions for edison that I've seen before include "Onside with great American inventor" , "inventive sort" , "He came up with microphone" , "Thomas ......, famous American inventor" , "Inventor of the carbon filament lamp, d. 1931" .)
