IN A WORD:
Ya. In Spanish, the word "ya" (which rhymes with the English word "jaw") is one of many uses and meanings. It can mean "already", "now", or "sure" to name a few. While those few translations may mean little to you, they mean a lot to me. The word itself is short and concise. I have never been either of those two things, so don't expect my ramblings to resemble the title.
