What is meant by "Singular rejection"?
This combination is used by a news anchor while describing the defeat of a leader. He used the following sentence:
"The leader received a singular rejection, as under his leadership, his political party received electoral defeats in a number of states."
As per this usage, it appeared that by "Singular rejection" he meant "total rejection".
However, when I checked the meaning of "Singular" at Cambridge dictionary or at Oxford dictionary, I didn't find any meaning of "singular" matching this context. I also searched at Google Ngram and I found that this combination is used a lot, but I didn't find any definition of this combination.
