accusative singular neuter; alternate form of adukkhamasukhaṁ, a substantive adjective
Analysis. a + dukkha + masukha, lit. 'non-pain non-pleasure': a negative (a-) prefix + dukkha 'pain' + ma (emphatic negation, 'not even') + sukha 'pleasure'. The compound denotes a state beyond both suffering and happiness, central to jhānic experience.
Etymology. The a- prefix is Indo-European negation (English un-, Greek a-); dukkha and sukha are Pali adjectives meaning 'painful' and 'pleasant' respectively. The middle term masukha uses the emphatic negator ma + sukha to intensify the contrast. This term reflects the Buddhist analysis of vedanā (feeling) into three or more gradations.
