I encountered the following sentence:
In programming, types are a means of classifying values.
According to "A Concise Dictionary of Correct English",
the plural of the noun mean, may be treated as a singular, as in a means to an end.
I wonder, in which cases it is appropriate to use indefinite articles with plural nouns. Is it reserved only for special cases or it can be used whenever someone feels that something is singular?
Fox example, subtitles distributed in a file look like a singular thing. So, at some point of my life, I wrote something like
The torrent has only an English subtitles, but I want a French ones too.
I still have a feeling that I did something wrong, but I don't know how to word it better.
