What is meant by “Singular rejection”

Question

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.

Answer 1

You may have missed it but in Cambridge Dictionary

singular adj

[FORMAL] of an unusual quality or standard; noticeable:

Being noticeable a synonymn of notable that according to Google Translator is

worthy of attention or notice; remarkable.

Maybe you can not assure that it was a total rejection but it was remarkable one.
