Intal is aninternational auxiliary language, published in 1956 by theGerman linguist Erich Weferling. Its name is an acronym forINTernationalAuxiliaryLanguage. Intal was conceived to unite the most important features of existing international auxiliary languages, likeEsperanto,Ido, Occidental-Interlingue,Neo,Novial andInterlingua, into a compromise system.

In the year 1956 Erich Weferling published the first version of his system Intal. The final version of Intal was published by Weferling in the year 1978.

Weferling saw his Intal as a compromise among the most important constructed languages, so he deliberately abstained from creating a complete dictionary of Intal. He regarded the existing different constructed languages as dialects of one common international language. He recommended using the vocabulary of the major international auxiliary languages, adapted to the orthography and phonology of Intal.

Weferling wrote most of his material on Intal in the language himself. In the year 1976 Weferling even published his autobiographyEk le vive de un oldi interlinguistiker (From the life of an old Interlinguist) in Intal.

After Weferling died in 1982, his efforts were nearly forgotten and the authorities of the surviving constructed language organizations showed no readiness to change their system according to Intal or to unify.

Intal uses theLatin script without special signs. The Intal alphabet has 23 letters, 5vowels (a, e, i, o, u) and 18consonants (b, c, d, f, g, h, j, k, l, m, n, p, r, s, t, v, y, z). The consonants q, w and x are only used in proper names and foreign words.

c is pronounced /ʃ/ (like Englishsh),g always hard (as in German),j as in French, andy andz as in English.

The stress of a word is on the vowel before the last consonant, unless marked by an accent as inidé andtabú.

Thedefinite article in Intal isle. It is used the same for singular and plural and for all genders.Theindefinite article in Intal isun. It is used for all genders, but only insingular.

Nouns have no specific ending. The usual euphonic ending is-e like:libre book,table table, but alsomanu hand andhotel hotel.

Naturalgender of living entities can be expressed by-o for male gender and-a for female gender: likekavale horse,kavalo stallion,kavala mare.

Theplural is marked by 's liketable's tables.

Thegenitive case is expressed by the prepositionde and with the definite article it becomesdel, likedel patro of the father. Thedative case which indicates theindirect object is formed by the prepositiona or with the definite articleal, likeal patro to the father.Theaccusative case which indicates thedirect object is identical with thenominative. Only when the word order is changed one can use theparticle-em, likeVu-em me danka It is you that I thank.

Adjectives end usually in–i as inNovial:boni good,beli beautiful. The ending-i can be omitted for euphonic reasons. The adjective is not changed according to case, gender or singular/plural. It is placed before thesubject.

Adverbs are mostly derived from adjectives by changing the ending to–im. Examples:bonim well,verim truly.
