adjective; nominative singular masculine with enclitic hi (emphatic particle)
Analysis. nibbāna + ogadha (in which ogadha is itself ava + gādha, 'sunk down into'); the compound expresses one deeply plunged into the cessation of suffering. The enclitic hi is emphatic.
Etymology. nibbāna: nis ('out of') + vāna ('blowing'), cognate with Sanskrit nirvāṇa—the fire blown out, extinction. ogadha: ava ('down') + gādha (√gādh 'immerse, sink'), with ava- providing the imagery of descent into depths. Related to English 'abysm' in force (depths plunged into).
