grandest?

As i've pointed out to you in other threads, you need to provide the sentence in which you have encountered a word or a term in order for anyone to help you.

In general, grand means something which is large, or fine--in the sense that it is a desirable item or event. Grandest is the superlative, which means that it would be the most desirable item or event. Please provide the original sentence in which you have read the word, so that a reasonable answer may be given you.
