naked: [OE] Naked goes back ultimately to Indo- European *nogw- ‘unclothed’, which also produced Latin nūdus (source of English nude [16]) and Russian nagój ‘naked’. The past participial form derived from this, *nogwedhos, passed into prehistoric Germanic as *naquethaz, which has subsequently differentiated to German nackt, Dutch naakt, Swedish naken, Danish nøgen, and English naked.=> nude
