>>79748317English started out as a Germanic language related to the old Norse languages.
Then the French conquered the island and introduced a bunch of French words and French dialect, changing the language tremendously. French itself is a romance language, which is properly considered a mix of Roman and Gallic tongues, and has a completely different root to Germanic languages. It wasn't a good fit.
For example, Germanic tongues love combining words to make longer words. For example, you can just shove the words for "house" and "ground" together to say "underground house". Basically treating words like lego blocks you can mix and stack. English somewhat inherited this property.
But the property of having lots of "silent letters" and overly convoluted spelling is a characteristic of French, which English unfortunately inherited in certain aspects too.
English speakers also got into the habit of shortening lots of words, so there's lots of contractions to make things fewer syllables.
In the recent past, the English got into the unfortunate habit of copying the faggoty way the royalty talks, which is where the "english accent" comes from. The way that Americans speak English is actually similar to the Late Medieval version of the language.
