Let us say that a couple is looking at the sunset. The man turns to his wife and says, "Beautiful." That is, although he could be referring to his wife, he is referring to the sunset.
In this situation, does the word "beautiful" refer only to the word "beautiful", or is the man really saying, "I think that the sunset is beautiful, don't you?"? That is, the single adjective is actually carrying a whole complete sentence within its mono-lexical universe. That is, "Beautiful" here is equivalent to "I think that the sunset is beautiful, don't you?"
Please answer this with only your own thoughts. No need to cite Ludwig Wittgenstein. I'm interested in what native and non-native English speakers think. What is your gut instinct?
