I just started to read The Prodigal Tongue by Lynne Murphy. She’s an American academic living in the UK (Specifically England actually) and writes from an interesting perspective. She acknowledges the often unproven or even plain wrong sentiments by many Brits that “Americanisms” are diluting the language, but gently shows examples of how in reality many examples are simply the language naturally evolving. On occasion the “Americanisms” turn out to be from Australia or New Zealand which I appreciated as they’re often ignored as places perfectly capable of generating their own variants of language (or yeast extract).
Anyway – only just started, but I thought I’d share the following:
Polyamory is wrong!
It is either multiamory or polyphilia but mixing Greek and Latin roots?
Wrong!
More fun and games here.

i am afraid the autokinete/ipsomobile has long since left the garage with regards to mixing latin and greek roots in the same word.
