Babm (pronounced [bɔˈɑːbɔmu]) is an international auxiliary language created by the Japanese philosopher Rikichi [Fuishiki] Okamoto (1885–1963). Okamoto first published the language in his 1962 book, Universal Auxiliary Language Babm, but the language has not caught on even within the constructed language community, and does not have any known current speakers. The language uses the Latin script as a syllabary: each letter marks an entire syllable rather than a single phoneme.
