# Lingua sistemfrater

Lingua sistemfrater (English: Language of Brotherhood), also referred to as Frater, is an a posteriori international auxiliary language created by Vietnamese translator Phạm Xuân Thái in 1957 as Frater (Lingua sistemfrater): The simplest International Language Ever Constructed. The language uses a largely Greco-Latin lexicon, and an Asian-influenced grammar.
Frater was one of the (comparatively rare) international languages created in Asia, and had a vocabulary of more than 6,000 words.

## Phonology and orthography

Frater used an orthography of eighteen letters from the Latin script: five vowels: a, e, i, o, u, and thirteen consonants: b, d, f, g, j, k, l, m, n, p, r, s, and t. These letters were enunciated as their pronunciations in the International Phonetic Alphabet, with the following exceptions:
* ⟨j⟩ is pronounced as [z];
* The letters ⟨e⟩ and ⟨o⟩ are pronounced as the diphthongs [ei] and [ou], respectively.
The stress is placed on the last syllable of the word; there are no silent letters.
