feminine noun, ablative/locative singular + emphatic particle
Analysis. sattiyā (ablative/locative singular of satti, 'spear' or 'power') + api (emphatic particle 'even, also'). The compound emphasizes the instrumental or causal role: 'by means of a spear' or 'through power/strength' depending on context.
Etymology. satti derives from Sanskrit śakti, from the root √śak 'to be strong, to be able'. The cognate is English 'shake' (from Proto-Germanic *skak-), which shares the Indo-European root sense of vigor and sudden force. The concrete image is of wielding power or striking force, whether literal (a spear's blow) or abstract (capacity, strength).
