I agree, josepp, that language is a kind of fossil, which can be broken open to reveal ancient usages and aspects of life. A long time ago I studied Linguistics & Phonetics at Uni, and was fascinated by all this. Geographically, for example, one can trace here in the UK the progress of various settlers and invaders by the place names. Here in Norfolk, 'thorpe' is an Anglo-Saxon word for settlement. I feel that Amber as a girls' name is with regard to the beauty of the fossil when used in silver jewellery, as it was by the Vikings/Danes in the Dark Ages. I have only recently become reconciled to the fact that language is constantly changing and 'mutating'. Common modern usage will confer status on a new expression or word. Instead of being irritated by 'ghastly' modern jargon, I now try to embrace it as 'evolution'. For instance, 'haitch' for 'aitch' jarrs dreadfully, but probably one day it will be universally accepted. Your thread is fascinating, thank you josepp!
