より used to indicate "from" I've usually seen used in the context of a person as the source giving something over, such as a gift. I assumed in that sense it was only more formal than から。
Yes, you are right. より used to formal, stiff and literary style writing.
I think that his question is "Why does used より(than) like "from" means?".
より does the origin in 因る(base on, cause of).
There is a difference in the meaning nuance, though it isn't conscious at the present day, I think.
Sorry, I mistook the way of the explanation. It was a misleading.
how do you say, "We will have a lot of fun in this show!"
私たちはこのショーをとても楽しみにしています。
Watashitachi ha kono shoo wo totemo tanoshimini shiteimasu.
ショーをとっても(すごく)楽しみにしてるよ!(casual version)
Shoo wo tottemo(sugoku) tanoshimini shiteruyo.
Wow, that's more detailed than I've ever seen those explained before. Thanks, Debezo!
You're welcome

, and
I remember an old topic about "~っす".
I forget which thread in this topic. and search bar isn't enabled...?
"~っす[ssu]" is a slanguish polite form by (体育会系) young mans. it has three advantages.
1. です/ますの使い分けの省略(unification of desu,masu)
思うっす[omoussu](masu for verb)
欲しいっす[hosiissu](desu for adjective)
京都っす[Kyouto ssu](desu for noun)
2. 活用形の省略(omit to conjugation)
行く -> 行きます -> 行くっす[ikussu]
食べる -> 食べます -> 食べるっす[taberussu]
する -> します -> するっす[surussu]
3.丁寧さと親しみの両方を兼ねる(politeness+friendly)
This expression is rudeness for old generation.
However, young generation too feel stiff to the correct polite speaking.
"~っす" has a bit of politeness and a bit of friendly for young generation.
It's so easy for busy young mans.
hope your help...
