Obsolete and Nonstandard Symbols
The IPA inherited alternate symbols from various traditions, but eventually settled on one for each sound. The other symbols are now considered obsolete. An example is ⟨ɷ⟩ which has been standardized to ⟨ʊ⟩. Several letters indicating secondary articulation have been dropped altogether, with the idea that such things should be indicated with diacritics: ⟨ƍ⟩ for ⟨zʷ⟩ is one. In addition, the rare voiceless implosive series ⟨ƥ ƭ ƈ ƙ ʠ⟩ has been dropped; they are now written ⟨ɓ̥ ɗ̥ ʄ̊ ɠ̊ ʛ̥⟩ or ⟨pʼ↓ tʼ↓ cʼ↓ kʼ↓ qʼ↓⟩. A rejected competing proposal for transcribing clicks, ⟨ʇ, ʗ, ʖ⟩, is still sometimes seen, as the official letters ⟨ǀ, ǃ, ǁ⟩ may cause problems with legibility, especially when used with brackets ( or / /), the letter ⟨l⟩, or the prosodic marks ⟨|, ‖⟩ (for this reason, some publications which use standard IPA click letters disallow IPA brackets).
There are also unsupported or ad hoc letters from local traditions that find their way into publications that otherwise use the standard IPA. This is especially common with affricates such as the "barred lambda" ⟨ƛ⟩ for .

Famous quotes containing the words obsolete and/or symbols:
“So much of truth, only under an ancient obsolete vesture, but the spirit of it still true, do I find in the Paganism of old nations. Nature is still divine, the revelation of the workings of God; the Hero is still worshipable: this, under poor cramped incipient forms, is what all Pagan religions have struggled, as they could, to set forth.”
—Thomas Carlyle (1795–1881)
“The use of symbols has a certain power of emancipation and exhilaration for all men. We seem to be touched by a wand, which makes us dance and run about happily, like children. We are like persons who come out of a cave or cellar into the open air. This is the effect on us of tropes, fables, oracles, and all poetic forms. Poets are thus liberating gods.”
—Ralph Waldo Emerson (1803–1882)
