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:
“Children don’t read to find their identity, to free themselves from guilt, to quench the thirst for rebellion or to get rid of alienation. They have no use for psychology.... They still believe in God, the family, angels, devils, witches, goblins, logic, clarity, punctuation, and other such obsolete stuff.... When a book is boring, they yawn openly. They don’t expect their writer to redeem humanity, but leave to adults such childish illusions.”
—Isaac Bashevis Singer (20th century)
“There are those who would keep us slipping back into the darkness of division, into the snake pit of racial hatred, of racial antagonism and of support for symbols of the struggle to keep African-Americans in bondage.”
—Carol Moseley-Braun (b. 1947)
