具足

"accomplished; etc."

Attested in early Chinese Buddhist literature such as the Dīrghāgama, possibly a semantic loan from Prakrit, e.g. Gandhari 𐨯𐨨𐨗𐨡𐨁‎ (samajadi, “to fall to”) as attested in the Khotan Dhammapada; in turn from Sanskrit संपद्यते (saṃpadyate), from सं- (saṃ-, “together; fully”) + √पद् (√pad, “to go”); cognate with Pali sampajjati (past passive participle sampanna) and Tocharian B phalasaṃpat (“prosperity”). The loan translation is notable for its precision in both the meaning and component-wise literal correspondence, as पद् (pad) derives from the PIE *pṓds (“foot”), in Chinese 足 (“foot”), while the character can also mean "full; adequate; sufficient; ready", etc.

具足

1. (literary) adequate; sufficient; abundant
2. (Buddhism) accomplished; complete; successful

具足

1. (literary) to possess; to be equipped with; to have

From Old Japanese 具足 (gusoku). First cited to a portion of the 続日本紀 (Shoku Nihongi) dated to 722.[1]

In turn, borrowed from Middle Chinese compound 具足 (MC ɡɨoH t͡sɨok̚, “to suffice; sufficient”, literally “provide, furnish + enough, abundant”), in evidence since at least the Lunheng of the first century CE.

Within Japanese, also analyzable as a compound of 具 (gu, “gear, equipment, furnishings”) + 足 (soku, “adding, making adequate”).
