Láadan

Láadan is a gynocentric constructed language created by Suzette Haden Elgin in 1982 to test the Sapir–Whorf hypothesis, specifically to determine if development of a language aimed at expressing the views of women would shape a culture; a subsidiary hypothesis was that Western natural languages may be better suited for expressing the views of men than women. The language was included in her science fiction Native Tongue series. Láadan contains a number of words that are used to make unambiguous statements that include how one feels about what one is saying. According to Elgin, this is designed to counter male-centered language's limitations on women, who are forced to respond "I know I said that, but I meant this".

Tones
Láadan is a tonal language. It utilises two distinct tones: The word "Láadan" has three syllables: "lá-" with the short vowel /a/ plus high tone; "-a" with the short vowel /a/ and no tone; and "-dan".
 * lo – or, a short, medium or low tone, represented by a single unmarked vowel
 * ló –, a short, high tone, represented by a single marked vowel

Láadan doesn't allow any double [i.e. long] phonemes. Whenever two identical short vowels would occur side by side in a single morpheme, one of them has to be marked for high tone. When adding an affix would result in two identical vowels side by side, an epenthetic /h/ is inserted to prevent the forbidden sequence. The language will allow either máa or maá, but not *maa. These combinations can be described as: (Some people analyze these tone sequences as tonemic as well, for a total of four tones.)
 * loó –, a long, low-rising tone, represented by a double vowel, the second of which is marked
 * lóo –, a long, high-falling tone, represented by a double vowel, the first of which is marked

Elgin preferred an analysis of the language as having no long vowels and a single tone, the high tone (distinguished from "neutral, baseline pitch"), but she acknowledged that linguists using other formalisms would be justified in saying that there are two tones, high and low (or unmarked or mid).

Vowels
Láadan has five vowels:
 * a –, an open back unrounded vowel (as English calm),
 * e –, an open-mid front unrounded vowel (as English bell),
 * i –, a near-close near-front unrounded vowel (as English bit),
 * o –, a close-mid back rounded vowel (as English home),
 * u –, a close back rounded vowel (as English boon).

Consonants
Láadan lacks the consonants. It uses b, d, sh, m, n, l, r, w, y , h with the same phonetic value as English. Three digraphs require further explanation:
 * th –, a voiceless dental fricative (always as in English think, never as then),
 * zh –, a voiced postalveolar fricative (as English pleasure),
 * lh –, a voiceless alveolar lateral fricative (as Welsh llan).

Grammar
Most Láadan sentences contain three particles:


 * The speech-act particle – this occurs at the beginning of the sentence and marks it as either a statement (bíi), a question (báa), et cetera; in connected speech or writing, this particle is often omitted. They are:
 * Bíi : Indicates a declarative sentence (usually optional)
 * Báa : Indicates a question
 * Bó : Indicates a command; very rare, except to small children
 * Bóo : Indicates a request; this is the usual imperative/"command" form
 * Bé : Indicates a promise
 * Bée : Indicates a warning
 * The grammatical tense particle – this occurs second in the sentence and marks it as either present tense (ril), past tense (eril), future tense (aril) or hypothetical (wil); without the tense particle, the sentence is assumed to have the same tense as the previous sentence.
 * The evidence particle – this occurs at the end of statements and indicates the trustworthiness of the statement. They are:
 * wa : Known to speaker because perceived by speaker, externally or internally
 * wi : Known to speaker because self-evident
 * we : Perceived by speaker in a dream
 * wáa : Assumed true by speaker because speaker trusts source
 * waá : Assumed false by speaker because speaker distrusts source; if evil intent by the source is also assumed, the form is waálh
 * wo : Imagined or invented by speaker, hypothetical
 * wóo : Used to indicate that the speaker states a total lack of knowledge as to the validity of the matter

Láadan is a verb–subject–object (VSO) language. Verbs and adjectives are interchangeable. There are no articles, and the object is marked by the -th or -eth suffix. The plural number is shown only by the me- prefix to the verb. The particle ra following a verb makes it negative. Separate clauses are joined by the particle hé.

 OBJ:object REQ:request ST 

Morphology
Láadan has an agglutinative morphology, and uses a number of affixes to indicate various feelings and moods that many natural languages can only indicate by tone of voice, body language or circumlocution.

The speech-act particle, at the beginning of a sentence, can also carry several suffixes, which expand on the overall state of the sentence. For example, bíi begins a statement, but bíide begins a statement that is part of a narrative; bóoth begins a request made in pain; báada begins a question that is meant in jest.

Pronouns
Pronouns in Láadan are built up from a number of constituent parts. The consonant l marks the first person, n the second person and b the third person. Usually, these are followed by the vowel e. The vowel a is used to designate someone who is loved (lhe- is prefixed to describe someone who is despised). The suffix -zh is used to mark a plural pronoun for numbers up to four, and -n for numbers beyond that. Therefore, lazh means "we, several beloved", and lheben means "they, many despised".
