Effective narration (7)

I believe the answer is:

telling

I believe this is a double definition.

'effective' is the first definition.
(similar in meaning)

'narration' is the second definition.
(I know that telling is a type of narration)

(Other definitions for telling that I've seen before include "Powerful; relating" , "Striking, having noticeable effect" , "Effective - narration" , "relation" , "of significance" .)

I've seen this clue in The Globe and Mail, The Telegraph, The Irish News and The Guardian.
