Went on about nominal script printing-type (5)
I believe the answer is:
ronde
'type' is the definition.
(I've seen this before)
'went on about nominal script printing' is the wordplay.
'went on' becomes 'rode' (I've seen this in another clue).
'about' indicates putting letters inside.
'nominal script printing' becomes 'n' (I am not sure about this - if you are sure you should believe this answer much more).
'rode' going around 'n' is 'RONDE'.
Can you help me to learn more?
(Other definitions for ronde that I've seen before include "Type" , "dance" .)
