Yi (Cyrillic)

Yi (Ї ї; italics: Ї ї) is a letter of the Cyrillic script.

It represents the iotated vowel sound , like the pronunciation of in Yiddish". It is used in the Ukrainian and Rusyn alphabets.

In various romanization systems, ї is represented by Roman ji, yi or i, but the most common is yi.

It was formerly also used in the Serbian Cyrillic alphabet in the late 1700s and early 1800s, where it represented the sound ; in this capacity, it was introduced by Dositej Obradović but eventually replaced with the modern letter ј by Vuk Stefanović Karadžić.

In Ukrainian, the letter was introduced as part of the Zhelekhivka orthography, in Yevhen Zhelekhivsky's Ukrainian–German dictionary (2 volumes, 1885–6).


Yi may refer to:

Yi (editor)

Yi is a text editor written and extensible in Haskell. The goal of Yi is to provide a flexible, powerful and correct editor core dynamically scriptable in Haskell.

Yi used to be a Haskell interpreter, very much like Emacs is an Emacs Lisp interpreter; however, the current version of Yi recompiles the code that describes its settings (including editing modes and extensions). Specifically, Yi is implemented as a small executable program which compiles through GHC the larger body of code which actually constitutes a useful editor; this small 'kernel' can repeatedly recompile (and thus type-check) the extensions. This makes it easy to dynamically hack, experiment and modify Yi despite it being written in a strongly statically typed language. Using Haskell as a first-class extension language means that other libraries and tools written in Haskell are also readily usable in editor code.

The long-term goal of the project is in essence to make Yi the editor of choice for Haskell hackers in much the same way that Emacs is the editor of choice for Lisp programmers.

Yi (Chinese surname)

is a Chinese surname, in Cantonese it is transliterated as Yick, the Chinese commercial code (CCC) of which is 2496. It is also rarely spelled as Yih or Ie, depending on where it is originated.

Yi (Confucianism)

Yi, , literally " justice, righteousness; meaning," is an important concept in Confucianism. It involves a moral disposition to do good, and also the intuition and sensibility to do so competently.

Yi resonates with Confucian philosophy's orientation towards the cultivation of benevolence (ren) and skillful practice (li).

Yi represents moral acumen which goes beyond simple rule following, and involves a balanced understanding of a situation, and the "creative insights" necessary to apply virtues "with no loss of sight of the total good. Yi represents this ideal of totality as well as a decision-generating ability to apply a virtue properly and appropriately in a situation."

In application, yi is a "complex principle" which includes:

  1. skill in crafting actions which have moral fitness according to a given concrete situation
  2. the wise recognition of such fitness
  3. the intrinsic satisfaction that comes from that recognition.

Yi (vessel)

A yi is a shape used in ancient Chinese ritual bronzes. It has the shape of half a gourd with a handle (often in the shape of a dragon) and usually supported by four legs. It is believed it was used to contain water for washing hands before rituals like sacrifices.

Yi (husbandman)

Yi ( Chinese: , ; millennium BCE) was a culture hero in Chinese mythology who helped Shun and Yu the Great control the Great Flood; he served afterwards as a government minister and a successor as ruler of the empire. Yi is also credited with the invention of digging wells (although Shennong is also credited with this).

Yi (dinosaur)

Yi is a genus of scansoriopterygid dinosaurs from the Late Jurassic of China. Its only species, Yi qi (Mandarin pronunciation: ; from and ), is known from a single fossil specimen of an adult individual found in Middle or Late Jurassic of Hebei, China, approximately 160 million years ago. It was a small, possibly tree-dwelling ( arboreal) animal. Like other scansoriopterygids, Yi possessed an unusual, elongated third finger, that helped to support a membranous gliding plane made of skin. The planes of Yi qi were also supported by a long, bony strut attached to the wrist. This modified wrist bone and membrane-based plane is unique among all known dinosaurs, and might have resulted in wings similar in appearance to those of bats.
