The World Orthography (WO) is an alphabet and transcription system based on the Africa Alphabet and the International Phonetic Alphabet. In Daniel Jones’s 1948 Difference between Spoken and Written Language, an adaptation of WO for English is given with the letters a b c d ð e ə f g h i j k l m n ŋ o p r s ʃ t θ u v w x y z ʒ. The capitals of ð, ə, ŋ, ʃ, θ, and ʒ are: Ð (shaped like Ƌ), Ə, Ŋ (shaped like large ŋ), Ʃ (shaped like sigma Σ), Θ, and straight-bottomed Ʒ (shaped like reversed sigma).
