I Don't Know the Name of this Literary Term!

[Ouisi]

I am looking at Dr. King's Dream speech and I am curious about the construct of many of his metaphors:

light of hope
night of their captivity
manacles of segregation
chains of discrimination
island of poverty
ocean of material prosperity . . .

and so on. There MUST be a term for this construction, but I can't find it. Anyone? Thank you in advance!!

not that I know of, they're just metaphors, but he's using repetition by giving them all the same form, and that's a common rhetorical device.

here - but I'm not sure a syntactic term was what you were after...?

[swedeheart]

...ha ha, nope, probably not - the title of your question being "literary term"...! Sorry! The thing is I think you're right, I'm 99 percent sure I've heard it - but needless to say I've forgotten:-(

Could it be "conceptual metaphor"?
