Ngehu

Ngehu (also called Lo Ngehu or simply Hu) is the main language spoken by the Ngehu people of Awa. Although little is known of the history of the language, both its oral history and its unusual structure point towards an origin as a consciously constructed language.

It is a right-branching, strongly isolating language, notable for its largely oligoanalytic lexicon, its complete lack of verbs other than the non-inflecting copula i, and the lack of any contrastive voicing, with all phonemes except /h/ being voiced. The lexicon is made up entirely of around 190 syllabic roots with a single basic meaning and these are combined in various ways to make more precise meanings. For example, the root zwa has the core meaning of 'water' but may, when qualified by other roots, refer to other liquids. Ni means, as its central meaning, 'air' or 'gas' but may also mean 'quality' or 'characteristic' (much as the word 'air'does in English as in 'an air of superiority') or simply anything that is invisible. Together these roots may be combined to form zwani 'rain' (a type of water defined by something to do with air, namely that it falls from it) or nizwa 'cloud, fog, mist' (a type of air defined by something to do with water, namely that it is filled with it).
