nominative singular feminine (likely a scribal corruption or rare form; closest attested form is saṅghāṭikā, a type of garment or robe)
Analysis. saṅghāṭa (a large outer robe) + -nikā (possessive/characteristic suffix, 'of or belonging to'); the form appears contaminated with or preceded by a demonstrative yadidam or similar particle in the manuscript
