zero can mean nothing.. so can zip, and as faldage points out,nada is the spanish for nothing..

some language double words to intensifiy them --goody-goody is one English example... goody-goody is very good, or gleefully good.. and while there are other examples, this is not the most common way to intensify.

usually we add er or est (fat, fatter, fastest, slow, slower slowest) with er being a comparative term, and est being the superlative term.

but we will sometimes use 2 or 3 words different words with the similar meanings to intensify a statement.
zero, zip, nada-- (three ways of saying i know nothing)--in Polish!

drunkness is a characterist that often is intensified by using several words or idioms..
Lord, he was drunk--three sheets to the wind, blotto, totally soused!
any one of those terms, (three sheets to the wind, blotto, totally soused, means drunk. strung together, they intensify the simple statement "he was drunk", and describe someone who is extremely drunk.
