Probably noun. Primitive form given as skalnâ, derived from the stem SKAL1 "screen, hide (from light)" (LR:386). Since -nâ is an adjectival ending, often taking on the meaning of a kind of past participle, skalnâ must mean "screened, hidden (from light)"; this has become a noun "shade, screen" in Nandorin.
The word scella, sciella alone tells us that ln is assimilated to ll in Nandorin, and as in dunna, spenna a primitive final -â, usually lost, seems to persist as -a following a double consonant. The shift of a to e in skalnâ > scella is parallelled by the similar shift in spannâ > spenna, q.v. However, such a shift does not occur in what might seem to be similar environments (before a double consonant?); cf. hrassa, not hressa, from khrassê. It would seem that e might further break up into ie, scella having the alternative form sciella.
