Question regarding language

[Peebothuhlu]

Question: How is it that languages keep their identity through their development?

Languages are invented by long periods of time by people who never met. Why is it then, for example, that Japanese does not have the sound L nor a letter for it? Nobody ever invented a word with that sound?

Well.... not that I, know much of anything about language ( I speak English and bad English.     )

But... languages don't keep thier identity ove time. They have always seemigly continued to change and grow/shift.

Look at Latin turning into both French and Spanish for example.

Perhaps with the modern advent of the interwebz well see more language 'blending together faster?

Cheers.

Not at work.
