esl acronym glossary

thank you to davesesl-er Medina for the clarification: "TEFL is just a generic term for Teaching English as a Foreign Language, whereas TESOL (Teachers of English to Speakers of Other Languages) is an official organization that you join and pay dues to. Attending a TESOL conference is a great way to get an overview of the field, I think. They have a huge convention in a different American city each year, usually end of March. If you really want to get into this game then you should check out TESOL."
