köken: Inherited from Old Spanish nada, inherited from Latin (nūlla rēs) nāta (literally “no born thing, not a thing born”), an extension of nēmō nātus (“not a soul”, literally “nobody born”). For descendants of the other part of the expression see Galician ren (“nothing”), French rien (“nothing”), Catalan res (“nothing; anything”). For the grammaticalization of an original nominal as a negative see…
aile: a nada de, ahí es nada, antes de nada, antes que nada, así que nada, casi nada, centro de la nada, como si nada, de la nada, de nada
köken: From ingen (“no”) + ting (“things”). The reason ingen ends with an -n and not with a -t is because it is actually the old neuter plural, thus this phrase originally means "no things". Compare allting, någonting.
Ingenting som vi gör är tabu, inget stoppar oss nu.
