[Spanish, nothing, from Old Spanish, from Vulgar Latin *(rēs) nāta, born (thing), anything (used in the phrase *nōn ... rēs nāta, not ... anything, literally "not a born thing," probably on the model of *hominēs nātī, anyone, literally "born people") : Latin rēs, thing + Latin nāta, feminine of nātus, past participle of nāscī, to be born; see genə- in the Appendix of Indo-European roots.]
