P.S. Using a familiar word in this situation is tricky, but it's harmless for repeated reference to say something like "Write $d(x) :=i$" without making up a word.

@Theo: All of these standard single words seem ambiguous in this specialized context. The closest might be "degree" if interpreted as "graded degree" in the associated grading. Otherwise it's probably clearer just to write $x \in \mathfrak{n}_i \setminus \mathfrak{n}_{i-1}$.
