So If I want to say, for example
In this episode of the famous cartoon",
and seeing that "cartoon" is masculine in French, do I say
Dans cet épisode du célèbre dessin animé
Dans cet épisode de le célèbre dessin animé.
I mean seeing that I'm using "de" as "of" and "le" as "the" and not for unspecified singular quantity, does the rule de+le=du still apply?
