I saw this example sentence in the entry for "almost" in Merriam-Webster dictionary:
It is an almost failure.
I think it should be:
It is almost a failure.
Can we use almost to modify a noun? I checked all the major dictionaries and all the dictionaries suggest that it is an adverb only, but in Webster Dictionary, I saw that they are saying that it can be an adjective too. What's the matter? The Cambridge Grammar of the English Language says that using it as an adjective is ungrammatical. Would anyone please clarify it? Can we that the language has changed? Or Almost can be adjective in North American English only? I am all in dark.
