Hebrew was literally synthesised a century ago. Language designers really did great work on taking a core of a dead language and proposing a cleaner, more modern version of it.

Russian and English never had this "rearchitecture-and-cleanup" moment. In fact, English borrows heavily from different languages (old german, old danish, latin, old french...) adding even more complexity. Russian borrows from greek, old slavonic (bolgarian), among others. So an advanced speaker/reader of these languages has to understand the influences.

A couple of years ago I tried learning some minimal Ancient egyptian. A fascinating language in its diversity. Middle kingdom egyptian, old and new kingdom written dialects. Then, there's a simplified cursive script which almost feels like modern writing.

> Russian is seriously messed up language.

Some (most?) national languages, which developed chaotically, are very illogical, with weird constructions and some inexplicable features (Russian and English are examples of this). Artificial/planned languages such as Esperanto are a different matter -- they are very easy to learn and very pleasant to the ear.

I have just watched a video about Hebrew spelling which suggests it is a lot more complicated than people realise.

Because Hebrew has been revived artificially.
