lujvo x_{1} (scalarvalued) is the magnitude of the vector of the differintegral (with respect to time) of order x_{2} of the displacement of x_{3} (object/point) relative to x_{4} (object/point/frame of reference; contextless default: origin) in coordinate system/frame of reference/as measured by x_{5} according to definition/standard/(meta)physics x_{6}, where the differintegral is taken with starting point x_{7}, in metric/by definition x_{8} This word uses three experimental gismu (with one experimental short cmavo for one of these): nicfa (nif), salri, cusna.
