The logo of Wikipedia is an unfinished globe constructed from jigsaw pieces—some pieces are missing at the top—inscribed with glyphs (letter or character) from many different writing systems.
Each piece bears a glyph (a letter or other character), or glyphs, symbolizing the multilingualism of Wikipedia. As with the Latin letter“W”, these glyphs are in most cases the first glyph or glyphs of the name “Wikipedia” rendered in that language. They are as follows:
Near the center is Latin ⟨W⟩. Above that is Japanese ⟨ウィ⟩ wi; below it are Cyrillic ⟨И⟩ i, Hebrew ⟨ו⟩ w, and (barely visible at the bottom) Tamil ⟨வி⟩ vi.
To the left of the ⟨W⟩ is Greek ⟨Ω⟩ ō, and below that are Chinese ⟨維⟩ wéi, Kannada ⟨ವಿ⟩ vi, and (barely visible at the bottom)Tibetan ⟨ཝི⟩ wi.
At left, from the top down, are Armenian ⟨Վ⟩ v, Cambodian ⟨វិ⟩ vĕ (lying on its side), Bengali ⟨উ⟩ u, Devanagari वि vi, andGeorgian ⟨ვ⟩ v.
The right-most column is Ethiopic ⟨ው⟩ wə, Arabic ⟨و⟩ w, Korean ⟨위⟩ wi, and Thai ⟨วิ⟩ wi.
The empty space at the top represents the incomplete nature of the project, the articles and languages yet to be added.
An initial design of the logo was created by Paul Stansifer, a then 17-year-old Wikipedia user, whose entry won a design competition run by the site in 2003. Another Wikipedia user, David Friedland, subsequently improved the logo by changing the styling of the jigsaw pieces so that their boundaries seemed indented and simplified their contents to be a single glyph per piece, rather than a jumble of nonsensical multilingual text.
