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.
Vem vet? Inte du. Vem vet? Inte jag. Vi vet ingenting nu. Vi vet inget idag.
never mind - it is not important (phrase used to reassure or comfort the person being addressed)
köken: From పరవా (paravā, “regard, respect, care for”) + లేదు (lēdu, “no”). Cognate with Kannada ಪರವಾಗಿಲ್ಲ (paravāgilla) and Tamil பரவாயில்லை (paravāyillai)
