Briefscript is a term coined by Reginal J. G. Dutton for an engineered language that, at least in written form, has much shorter words than most natural languages. Some briefscripts are also speedtalks, i.e. languages that are also very concise in spoken form, but that is not necessary. Some briefscripts use the Latin alphabet as a syllabary; to this purpose, a highly restricted phonology with a very small phoneme inventory is used, i.e. the exact opposite of R. A. Heinlein's speedtalk idea (which uses so many phonemes that each morpheme of an oligosynthetic language can be just one segment long).
