Hi,
When I look up "a," one of the definitions says:
used before nouns that are usually uncountable when other information about the quality, feeling etc is added by anadjective, phrase, or clause:
But I am having difficulties to understand this rule. Is there any basic criterion that I can rely on to judge if this rule can be applicable?
Let's say, "rain" is usually uncountable but I think it's OK to say, "it was a heavy rain" or "a good knowledge" while I don't think you can say, "a good information" or "a expensive equipment." Why??
Thank you,
M
