Intensive so

Hi, I was working on translating something into Quenya and needed to find a word for "so" or "such" when used as an intensive modifier like "very" (As in "I ate so much") I found a word for "so", but it seemed to mean something more like "as" As a secondary question, which word for "so" should be used for the one that kind of means "as"? There are a lot and I can't figure out which one to use. [Just a note, out of the two questions, the first one is more pressing than the second]

There isn't a really direct match for "so" or "such", but I think langë or an- will do. If you like none of them, you can search here--

lange and an-/am- are good options, depending on the exact situation I would also look at ta. For the second kind of "so" I would use síve ... tambe.
