Did you know that leraar is a Dutch word? A new API, LangID can help you with those pesky language identification problems. Feed it a string of text and the API returns the name of the language, its ISO code and even an image of the flag for a country that speaks the language (the latter could be a hot-button political issue--watch out). You can choose your output as either XML or browser-friendly JSON. (More details at our LangID API profile.)
