archaic portuguese...

[pc2]

salutations,

we would like to know (just for curiosity) where we can find some interesting information about the archaic form of portuguese (the one that developed from the galician-portuguese form). we don't know if we are referring to it by its correct name, but we are talking about the portuguese of the time the Portuguese came here to Brazil. it's very different (in part, in the ortography) from the Modern Portuguese, for example, compare "asumpçam" with "assumpção" --> "assunção" (Modern Portuguese) - (from Latin assumptio?).

a very interesting ortographic fact is also the use of "v" to write "u", for example, "PORTVGVAL" --> "Portugal", and the use of final "oa" instead of "ua" (Modern Portuguese) to denote oral growing diphthong; and also the use of "am" to denote the portuguese nasal decreasing diphthong "ão".

note that, in Modern Portuguese, "ão" denotes a stressed oral decreasing dipthong, and "am" denotes an unstressed oral decreasing dipthong. it's just a thought, but is it possible that the words finishing with "ão" were written with "am" and read with tonicity in the penultimate syllable?

compare this interesting example:
ARCHAIC: "Arte de grammatica da lingoa mais vſada na coſta do Braſil" (Anchieta, 1595) is the title of the first book on Tupi grammar, by the Portuguese priest and grammarian José de Anchieta, and its title means "grammar art of the most used language in the coast of Brazil".
MODERN (the exact same phrase, and read in the exact same manner, but written in an ortographically different way): arte de gramática da língua mais usada na costa do Brasil.

there is also another detail that we don't know if we are misunderstanding, but it's the use of "ſ" (upper half of the notation for both definite and indefinite integration (the last one is also called antiderivation or antidifferentiation), in Mathematics) for the phoneme "s".

well, what we are asking here is if there is any place that we can find the information above (or, a site about Archaic Portuguese), or if there is someone here who can answer these questions for us...

TIA,
