Láadan
Summary
Láadan (/ˈlɑ˦ɑˈdɑn/) 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".
Láadan is a tonal language. It utilises two distinct tones:
lo /lō/ or /lò/, a short, medium or low tone, represented by a single unmarked vowel
ló /ló/, a short, high tone, represented by a single marked vowel
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".
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:
loó /lǒː/, a long, low-rising tone, represented by a double vowel, the second of which is marked
lóo /lôː/, a long, high-falling tone, represented by a double vowel, the first of which is marked
(Some people analyze these tone sequences as tonemic as well, for a total of four tones.)
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).

Constructed language
A constructed language (shortened to a conlang) is a language whose phonology, grammar, and vocabulary, instead of having developed naturally, are consciously devised for some purpose, which may include being devised for a work of fiction. A constructed language may also be referred to as an artificial, planned or invented language, or (in some cases) a fictional language. Planned languages (or engineered languages/engelangs) are languages that have been purposefully designed; they are the result of deliberate, controlling intervention and are thus of a form of language planning.
Lojban
Lojban (pronounced ˈloʒban) is a logical, constructed, human language created by the Logical Language Group which aims to be syntactically unambiguous. It succeeds the Loglan project. The Logical Language Group (LLG) began developing Lojban in 1987. The LLG sought to realize Loglan's purposes and further improve the language by making it more usable and freely available (as indicated by its official full English title, Lojban: A Realization of Loglan).
Engineered language
Engineered languages (often abbreviated to engelangs, or, less commonly, engilangs) are constructed languages devised to test or prove some hypotheses about how languages work or might work. There are at least three subcategories, philosophical languages (or ideal languages), logical languages (sometimes abbreviated as loglangs), and experimental languages. Raymond Brown describes engineered languages as "languages that are designed to specified objective criteria, and modeled to meet those criteria".
