@alexandra Exactly, you are correct. But another way of saying this is: may be if a word could express 'every and all meaning', then every new day would have looked like the previous one. Because then 'Day' this word will express all meaning of all day... and there would be nothing more to explain or express about each new day... (am I being too philosophical? Then tell me and I'll try to explain more, what I am saying. :) . But this is the thing, our language is incomplete, and we need to talk more to understand each other, which is a good thing)

It's a bit strange for me why you think "if words could express everything, we would have gone silent after a few days"? Even if we tell about all things during this few days new days get a new words to say about, isn't it?

PS: written in haste, don't want any correction. Thank you.
