masc instr sg of sukha (adj); nt instr sg of sukha (adj); nt instr sg of sukha (noun)
Etymology. su- 'well, good' + kha 'cavity, opening' (lit. 'having good space'). The word originally denoted physical ease and openness; cognate with Sanskrit sukha, from Indo-European *sṷ- 'good' (English 'swoon', Greek eu-), and kha from *kh- 'to split, open' (no direct European cognate, but the imagery of openness and unobstructedness persists in the Pali philosophical sense of ease as absence of constraint).
