whether, or something
-라든가 is used to list various descriptions that can be selected. (ㄴ)다든가 follows verbs or adjectives to list various propositions that can be selected. These descriptions or propositions are mainly theoretical, which is the distinction between this grammar and -든가.
-라든가 is a contraction of '-라고 하든가' and (ㄴ)다든가 a contraction of '-(ㄴ)다고 하든가'.
