Hello. My mother tongue is British English. I speak several European languages, so I might describe myself as a polyglot manqué. My professional career has included writing and reviewing many hundreds of documents by or for people for whom English is a second or third language (for a few, perhaps a higher ordinal applies). I have been an en.wikipedia and en.wiktionary contributor on an occasional basis for many years.
Check that out for my latest ideas on Simpler English and work on making BNC1994 wordlists freely available (both written and spoken, BNC fans!)
