Language nerd, especially grammar and pronunciation of any language
Teacher of English as a Second language since 2004 (professional language nerd)
I've taught in South Korea, Turkey and Canada, from kindergarten to university level, and in-house corporate instruction
My two native languages are English and French (though my French is on the iffy side of iffy now) and I've studied German, Dutch, Korean and Turkish
I've trained TESL teachers and hold a B.A. in Linguistics
