Uncountable nouns are usually used without an article.
Superlatives require definite article. What comes out of these 2
rules when superlative meets uncountable article? We need an
example, I hope it is good: This lake has clear water. This lake
has clearest water. This lake has the clearest water. When I
searched the web I found both "clearest water" and "the clearest
water". I read on this site, that in informal speech the is
frequently omitted, so let's concentrate on formal speech or
writing. If there is Am/Br specific it would also be
interesting. Please comment on the examples and in general.
Thanks.
