|This is just one variation of the sign. I sign WHY differently.|
American Sign Language is not a written language. Therefore when signs are in written format, it's referred to as 'gloss' because you are not translating the language - you're merely trying to write it down in written format. Gloss can even portray questions versus statements (as in what is being done with your body language and facial expressions).
It's important to note that ASL is not a word-order language, rather ASL is inflection (like some Asian languages). English on the other hand is word-order. The other important concept I'm always teaching in class is that ASL does not have a word-to-word correlation with Engish. Therefore, while many times you can ask 'what the sign for [fill in the blank word]?' - there are just as many times that there isn't a sign because signs are concepts (not necessarily words).
For example, going through college years ago, I wanted to know the sign for 'corrupt' - at the time my friend said, "well explain it to me. WHY do you want the sign?" So I explained the story to her and she explained to me how to sign that concept. Ding Ding Ding - it was a light bulb moment - Right! There isn't a word-to-word correlation so of course there doesn't always have to be a 1:1 correlation.
So WHY do I write my signs in capital letters - now you know :)
