Root of LanguageTANAKA AkioThe root of language is in the discreteness. All the information of language are generated from this simple structure which supposition is derived from Flux Conjecture, Lemma 1 and Lemma 2.

Discreteness of Language
Flux Conjecture(Lalonde-McDuff-Polterovich 1998)Image of Flux homomorphism is discrete at H1(M; R).Lemma
1 Next two are equivalent.
(i) Flux conjecture is correct.
(ii) All the complete symplectic homeomorphism is C1 topological closed at symplectic transformation group.Lemma
2 Next two are equivalent.
(1) Flux conjecture is correct.
(ii) Diagonal set M
M×M is stable by the next definition.Definition
L is stable at the next condition.
(i) There exist differential 1 form u1, u2 over L that is sufficiently small.
(ii) When sup|u1|, sup|u2| is Lu1
Lu2 for u1, u2 ,there exists f that satisfies u1 - u2 = df .Explanation 0

(L2, L2) means the next.There exists complete symplectic homeomorphism that is ψ(L2 ) = L2andψ*L2 is isomorphic with L1.Impression Discreteness of language is possible by Flux conjecture 1998.
