sacarna (adverb): soon, after(wards), in the near future.
sacarna már evá mbet rassá tenámbes
soon it cover.PERF and become.POT rain.ESS
“it [will] become cloudy soon, and [maybe] it will rain”
sacarna is used to situate events at some largely indeterminate point in the near future. It voids the need for use of the future particle sat, and can be used with any aspect/mode configuration, including the perfective (as a more realis AM category) and the potential, which can be used for more vague predictions, as in the example sentence above.
