English is a living language, and it “misuse” and bendabilty is what makes it such a beautiful, joyful language. Just my foughts, innit.
I agree with this, and have no problem with meanings evolving over time. So, for example, I don't think 'decimate' has to mean 'to reduce by one tenth' nor 'quarantine' to mean 'detain for 40 days.'
However, I do have a problem when people take two different words with distinct meanings and conflate them as if they mean the same thing. 'Disinterested' and 'uninterested' have different meanings, as do 'reactionary' and 'reactive'. 'Momentarily' means something different from 'in a moment.'
Conflating these words reduces the precision of language and impedes understanding, which makes me sad .
