flecu - fle- gismu

x1 is a current/flow/river of/in x2 flowing in direction to/towards x3 from direction/source x4.

[x1 is a stream of x2; x2 is a fluid Gas or liquid. (= selfle for reordered places); x1 flushes toward x3; flush (= caifle, sukfle)]; See also rirxe, senta where no directionality is implied, rinci, xampo, dikca, sakci, gapci, litki, ciblu.
