Neo is an international auxiliary language created by a Belgian diplomat of Italian descent Arturo Alfandari.



The first draft was published in 1937 by Arturo Alfandari but attracted wider attention in 1961 when Alfandari published his books Cours Practique de Neo and The Rapid Method of Neo. The works included both brief and complete grammar, learning course of 44 lectures, translations of literary works (poetry and prose), original Neo literature, scientific and technical texts, idioms, detailed bi directional French and English dictionaries. The total volume of the publications was 1304 pages, with dictionaries numbering some 75 000 words. Such a degree of details was unprecedented among constructed languages of the time.

The language stands in the tradition of international auxiliary languages such as Esperanto or Ido, with the same goal - a simple, neutral and easy to learn second language for everybody.

Neo attracted the interest of the circle around the International Language Review, a periodical for IAL proponents whose publishers co-founded the international association of neists - Friends of Neo (Amikos de Neo) with Alfandari; the organization also published its bulletin, the ˝Neo-bulten˝. For a few years it looked like Neo could be a serious competition to Esperanto and Interlingua.

However, Alfandari's health worsened and to avoid disappearance of his language, he founded second, more serious organization - the Academy of Neo (Akademio de Neo) with the task of regulating, nurturing and spreading the language; but the organization turned out to not to be very successful and the progress was cut short by Alfandari's death in 1969 and the language was mostly forgotten.[1]


Grammatically, the language is mostly influenced by Ido and Esperanto; but also, in some characteristics such as a plural -s and natural-appearing pronouns, by the naturalistic IALs like Interlingua and Occidental.

The cover of The Rapid Method of Neo

The way of forming of the vocabulary and the preference for short, monosyllabic words show a substantial Volapük influence, but unlike its roots which are often changed and mutilated beyond recognition, the Neo roots are easily recognizable as being clearly romance.

It is also notable for its terseness, which exceeds that of English or any International auxiliary language (IAL) of the a priori type, which makes it very compact and brief in expression, and for the facility of its grammar whose overview occupies only two pages.

The Lord's Prayer:

Na Patro ki sar in cel,
siu ta nom santat.
Venu ta regno.
Siu fat ta vol,
asben in cel, as on ter.
Na shakida pan ne diu oje.
E ne pardonu na debos,
as nos pardonar na deberos.
E no ne induku in tentado,
mo ne fridu da mal.

Wanderer's Nightsong (German: Wanderers Nachtlied) by Johann Wolfgang von Goethe:

Noxkant del wander
On tot cimos sar
In tot et lokos
Tu sentar
Apene un soplo;
Nel bosko l'ezetos tacar.
Duldu, sun tu
An ripozor.
Wanderer's Nightsong
Up there all summits
are still.
In all the tree-tops
you will
feel but the dew.
The birds in the forest stopped talking.
Soon, done with walking,
you shall rest, too.
Wanderers Nachtlied
Über allen Gipfeln
Ist Ruh,
In allen Wipfeln
Spürest du
Kaum einen Hauch;
Die Vögelein schweigen im Walde.
Warte nur, balde
Ruhest du auch.

The Task by Douglas Blacklock:

Lo Tasko
Vortos sirvar asben informo
As tromplo e traplo.
Deo volvar lo kor del omos
Dal veg de sklavos
Al veg de Frido.
Lo brev simpla vortos de Neo
Utin ne inspiru
L'uto justa
De Parlo e Skribo.
The Task
Words are used both to inform
And to deceive and ensnare.
God turns mens hearts
From the path of slavery
To that of Freedom.
The unadorned short words of Neo
May become an inspiration
To the rightful use
Of Speech and Writing.

Lo diplomata linguos

Latin sir, us l'endo del issepa seklo, l'oficala linguo de diplomatio. Latine so redaktir lo tratalos e l'akordos e so skambir lo komunikos inte governos. Lo last gran tratal ridaktat latine sir lo de Westfalio, in 1648; depdan kauzel preemintenta plas trenat pe Franso, latin pokpoke cedar plas a fransal; e fransal restar us l'enso d'et seklo - us 1918 - lo diplomata linguo, lo linguo de tot internasyona medos.

Ab 1918, lo diplomata linguos jar du: fransal e anglal. In et du linguos, sir menat lo negosados pol Versailles-Tratal e pol osa paxtratalos de 1919 e sir ridaktat et tratalos, amba lingos fande fid; dok no sen inkonvenos, lo du textos pande somyes determeni def interpretazos.

Do 1945, espanal, rusal e cinal sir an admitat as aficala linguos. Nos nun nel epok de tradukeros e interpretos.

(Gino Buti)

Ka sor l'avena diplomata linguo?

Sar nel internasyona riunos, konferensos e kongresos, dey num pluar idide, ke lo neso d'un monda adlinguo se far senti pluste.

Nilo samtempe plu groteska e plu afligifa qam lo spekto ofrat pel kongresistos munat kon udokaskos, ki tentar, sen sem riusi, kapi lo diskorsos pronuncat in def lingos. Diskorsos tradukat aste pe interpretos, dey lo melestas sar force, konforme l'itala dikton: tradukeros, trazeros.

Es so exijur dal parpreneros lo kono d'un komuna adlinguo, ke zi pur apreni kon infana izeso, so fur ilke un enorma ekonomio de temp, dengo ... e de malkomprenos.
