Nuanced translation of dialogue ignores it (6)
I believe the answer is:
subtle
'nuanced' is the definition.
(I've seen this in another clue)
'translation of dialogue ignores it' is the wordplay.
'translation of dialogue' becomes 'subtitle' (a subtitle translates dialogue).
'ignores' suggests deleting specific letters.
'subtitle' with 'it' removed is 'SUBTLE'.
(Other definitions for subtle that I've seen before include "Very fine, difficult to perceive or appreciate" , "Fine, delicate or hardly noticeable" , "Bustle in crafty, angenious way" , "Able to make fine distinctions" , "Delicate, with fine nuances" .)
