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?
We have overlapping terms that describe things we already have terms and words for.
We need to think of newer words, than just applying an already made word to mean several different things.
I agree that this is annoying, but I think your belief about its cause might be a bit of an assumption - as I understand it, this kind of thing is usually caused when dialects have different meanings for the same word and then they merge, rather than a simple lack of creativity.
