jezik, govor, besjeda. If you're asking what is the word word in Croatian it'd be rijec
There is no such thing as a language without words. Even Sign Language uses words.
Look it up in the dictionary, whoever asked this question!
Most every Hebrew word has a root, which is set of 3 consonants. (Some roots have 4, and a few foreign roots have 5.)The root is the building block of the Hebrew language. It is the same in Arabic.
There is no known language that has no word for no. Sorry.
