here’s some I’ve noticed:
- Why do we have articles? They’re mostly useless.
- Why do capital letters exist? (this is mainly an issue with the Greek and Latin alphabet though)
- Why is “I” used plural for verbs?
- Why are there so many inconsistent prefixes for tenses?
- 's is used for possessives. However, “its” is the possessive and “it’s” is not.
- Why do we have another set of pronouns for possessive pronouns?
- Why do adjectives go before the noun compared to basically every other language?
There are so many, and I think it comes down to the fact that English is a mix of at least two language families and how a bunch of grammar nerds overcorrected it.
