s=th/t/l/r

...from the Spanish, the s is lisped/slipped into th, part of the train of t/tl(N). if it happens in one language it can happen all over, one of the advantages of having only one Planetary Language, which is not PIE anymore, it has a name, Nauatl(N)=4 waters(Biblical Edenic Rivers=r)iue(r)li=iueli/N=powerful). .....side(E)=s/th/tide(N/Letra)=tit/de(E/Latra)=titla/titlani(N)=litany(between/messenger),=coincide/suicide/accident/incident/occident(direction/side)=-cide/side(E)=sideral(E)=pertaining to the stars,=sit/derall/i (Letra)=s/citl/d(e)ra/l/i(Letra)=citlali(N)= star(E)=zilar(Basque)=silver(E), but back to -cide particle, titla/titlani/litany. .....ceti/cetia(N)=sit/set(E)=settian(OSaxon)=set(E)=sit(E)= sittian(OSaxon). a candidate for -cide/side, but the meaning is there only for sitar/guitar/settle/and the frequentive secret/cec(r)etia(N)/settle, not as emphatic between=titla(N)=tide/tithe/tidings/title/titivate/triturate(E) as, cide/side/accident/ incident/incite(E)=set(E)=ceti/cetia(N)in rapid motion, hmmm, both titla/titlani(N) and ceti/cetia(N) roots are valid. duality of Language exists so talk/spirit/spiel will never fail us, designed to survive, as we, in our grosser parts, are not designed to endure=in toloa(N)=the tolerance/dolorous(E).
