Oh my God, my species is doomed.

[Lartnev]

English is one of, if not THE most flexable languages in the world. I mean we don't have to have adjectives and verbs which agree in number, gender and case like in Latin, and many languages such as French and German require a match for gender (ie le and la, das, die and der). But I suppose that's more grammar than spelling.

As far as spelling itself goes, if you're told how a word is spelt, that's how it's spelt. There doesn't need to be any logic, just that's how it's spelt, simple as that. Modernisation of a language is the choice of words for the times, not being lazy with how you spell them.
