Latin sin Flexion is an auxiliary language.

The language, originally created by Giuseppe Peano, is an attempt to strip Classical Latin down to its simplest possible grammar while keeping its vocabulary recognizable, making a language learnable in hours rather than years.

This page documents the Latin sin Flexion(Lø) variant that favors compactness by removing ending vowels and repeated consonants. When multiple Latin forms can express the same concept, Lø chooses the shortest form that remains recognizable and unambiguous. Vowel retention is a minimum-length safeguard in small words, not a word-class signal. This is Latino Sine Flexione, only moreso.

Pronunciation

Latin sin Flexion favors the old Latin pronunciation, consonants are sounded as in English with the exception of c that is always sounded like k, as in can and cat. Vowels are pronounced as indicated below:

• a, as in father.
• e, as in they.
• i, as in machine.
• o, as in tone.
• u, as in rule.
• y, as French u.
• j, as y in yes.
• ae, as i in aisle.
• oe, as oi in boil.

When the ending vowel of an article and starting vowel of the next word is the same, the first word can be contracted, like te es(you are) to t'es and da ad(give to) to d'ad.

Syntax

The order of words is so nearly similar to the English order of words that one may safely follow that usage without fear of being misunderstood or being too greatly incorrect. Most grammatical elements are not necessary, declension and conjugation are eliminated.

The subject tends to come first, the predicate last. The word most expressive of the thought uppermost in mind will likely come first and the others follow in their natural sequence. Lø sentences adheres to a rigid Subject Verb Object structure, and questions, Verb Subject Object.

noun-phrase   ::= prep? determiner? NOUN adj? help

declarative   ::= noun-phrase VERB noun-phrase? ; SVO
interrogative ::= VERB noun-phrase noun-phrase? ; VSO
                | INTERROG VERB noun-phrase?    ; question-word
imperative    ::= VERB noun-phrase?             ; subject implied

sentence      ::= declarative | interrogative | imperative

Nouns

Any Latin dictionary gives two forms for each noun, the first form is called nominative, the second genitive. Lø nouns are derived from the Latin dictionary stem, not necessarily the historical root:

There is no grammatical or artificial gender. Natural gender is indicated by different names if these exist, like patr(father) or matr(mother). Otherwise, gender is indicated like can mas(male dog), can femin(female dog).

There are no cases. The English genitive is made with de, as in ped de homin(the man's foot). Plural can be marked, but it is omitted when not necessary: fils(sons), tres fil(three sons) or plur fil(multiple sons).

gender     ::= NOUN "mas" | NOUN "femin" help
quantifier ::= NUMERAL | "plur"
plural     ::= NOUN "s"
countable  ::= quantifier NOUN | plural
genitive   ::= NOUN "de" NOUN

Articles

There is no definite or indefinite article. When it has the value of a pronoun and its use is necessary, it is translated with a pronoun, like il or un. :

• D'ad me librs, give me books.
• D'ad me libr, give me a book.
• D'ad me hoc libr, give me the book.
• D'ad me il libr, give me that book.
• D'ad me ils libr, give me these books.

quantifier    ::= NUMERAL | "plur" help
demonstrative ::= "hoc" | "il" | "ils"
determiner    ::= (demonstrative | quantifier) NOUN

Pronouns

Possessive pronouns are simply: de me(my, mine), de nos(our, ours), etc.. Reflexive pronouns are made of se(myself, himself, herself, itself..) and de se(of one's self). Capitals can sometime mark personification or proper-noun status, ordinary nouns stay lowercase even in elevated prose.

pronoun    ::= "me" | "te" | "il" | "nos" | "vos" | "ils" | "id" help
reflexive  ::= "se"
possessive ::= "de" pronoun | "de" reflexive

Adjectives

Adjectives always follow the noun they modify, like avs veloc(swift birds) and are are not modified by plurality. Adjectives may also be formed by means of de, like de fratr(fraternal). The prefixing of the negative ne or non may ordinarily be used to denote the contrary. The preposition sin may be used to denote lacking, like the suffix "-less" in English.

In some cases, the "noun adjective" order may be flipped, like with Bon-Auror(Good morning), in such a case, the adjective is connected to the noun that succeeds it, with an dash. This form can also be used to coin new phrases, like Veloc-Avs (The Swift Birds).

• Brev, short.
• Plus brev, shorter.
• Maxim brev, shortest.
• Tam brev quam, as short as.

For the comparison of adjectives, superlatives are used like: plus(plus), mult(much), maxim(most)..

degree      ::= "plus" | "minus" help
negative    ::= "non" ADJ | "sin" ADJ
adjective   ::= ADJ | "de" NOUN

comparative ::= degree ADJ "quam"   ; more/less .. than
equative    ::= "tam" ADJ "quam"    ; as .. as
              | "tant" ADJ "quant"  ; as much .. as

Verbs

The Latin vocabulary gives the present indicative and the present infinitive. By dropping the ending of the infinitive -re, the Lø form is obtained. The form of the imperative is the same as the one for the present. Sometimes the idea of the past is indicated by a word of the sentence and in such case there is no need to inflect the verb.

When it is necessary to indicate the past, this can be done by an adverb as jam(already), tum(then) or by e(have) preceding the verb:

• Nos e am, we have loved.
• Me jam am, I loved.
• Te tum am, you loved.

When it is necessary to indicate the future, it can be done by the adverbs vol(will) and deb(must) like in English, or by i(shall) preceding the verb:

• Nos i am, we shall love.
• Me vol am, I will love.
• Te deb am, you must love.

The potential form is indicated by pot, like pot exprim(can express). The subjunctive has no special ending, its idea is expressed by the use of conjunctions like si, que, quod.

The passive form is done by the past participle and the verb "es", to be: es scrib(is written). It may also be rendered by "qui" and a relative clause: fil es qui matr am(it is the son whom the mother loves).

past        ::= ("jam" | "tum" | "e") VERB help
future      ::= ("vol" | "deb" | "i") VERB
potential   ::= "pot" VERB
negative    ::= "ne" VERB
subordinate ::= ("si" | "que" | "quod") sentence
passive     ::= NOUN "es" participle
              | NOUN "qui" sentence

Adverbs

Adverbs from adjectives are obtained by means of in mod(in a way of), like in mod fratern(fraternally).

• alib, elsewhere
• ben, well
• cert, certainly
• erg, therefore
• mal, badly
• mult, much
• nimis, too much
• non, no, not
• quam, as, than
• quas, almost, nearly
• nam, because, for
• satis, enough
• tut, safely
• usqu, till, up to
• vald, greatly, very, very much

Adverbs to do with time:

• jam, already
• in fin, at last
• hod, today
• ant, before
• iterum, again
• cras, tomorrow
• her, yesterday
• interim, meanwhile
• nunc, now
• post, after
• nuper, lately, recently

• semper, always
• subit, at once, immediately
• prim, at first
