A neji (pronounced /nɛdʒi/ "nedgy"; for "near-equal JI") or a quasi-equal rational tuning is a rational approximation of an EDO.
In Zhea Erose's primodality theory, nejis can be used to explore a prime family (see primodality), while keeping the transposability, scale structures, rank-2 harmonic theory, notation, etc. associated with that edo. (The neji's denominator need not be prime but Zhea often uses semiprimes pq.) Zhea Erose's theory also deals with modulations between different prime families, and combining different prime families into one scale.
History
The neji is probably first proposed by George Secor in 2002[1].
