nusquam, nihilum, nihil are the three conjugations of the latin word for nothing. I also added a link to a translation website in case you have further questions.
Nihilum and nihil are good words for 'nothing', as is 'nil'. 'Nusquam', however, is an adverb meaning 'nowhere'.
Do not trust any on-line translation site for Latin. They are all notoriously inaccurate.
The latin for "nothing" is nihil, which is the root of the English word nil.
