Sure. Apparently for some languages, the context will tell you what the word is. AFAIK, Hebrew has-triliteral roots (as Arabic does) and thus there really isn’t all that much need to have vowels written in. For some texts, though, there are vowel annotations.
Since English doesn’t have the same root system as Hebrew, the example you give serves to show what an English word looks like without a vowel but doesn’t really show you how it works. Try this example instead:
It’s much clearer what’s missing, isn’t it?
There are quite a few different approaches to writing a language. Check out the categories in the Omniglot.
