discursive: static/specific/unchanging - dynamic/mutable/variable/slightly different/vaguer.
This involves the concept of how ‘mutable’ or changing something is. In «mi morji lodu'u mi sa'orgau le loldi li 45 jy vo'e'e.a'a'enai» (I tilt the floor by 45 degrees), «vo'e'e» refers to the x2, but an old version of x2; the tilt is ‘by’ 45 degrees even when filling in at ‘at angle’ place because the frame of reference is itself - but obviously not non-dynamically itself, which would not make sense in this usage. A sumti could refer to an imprecise category of values that are different at different points in time. This may be like referring to a git or darcs repository, but in a dynamic sense, the sumti doesn't have to be tied to a particular revision, but each time the sumti appears it can be instatniated with a different revision, but in a static sense you are emphasizing that likely more of the context is not changing, as in traditional definitions of the law of non-contradition. A git branch would be less dynamic than a git repo but more dynamic than a git tag. In differential equations, it can be useful to define differentials as actually functions of a given ‘base’, e.g. dy for a given x as dy(Δx, x), especially when writing proofs involving lim(λΔx → …, 0). Δx would be a ‘hidden’ part of the context that might vary. Another analagy is FRP, with self-mutating functions or time-varying values. See also: vabysto (static), vabycne (dynamic).
