ISO 639-1 Languages Containing Each Letter A-Z

Can you name a language that starts with A and contains B? Now, can you do this for every combination of two letters, taking into account all languages with a specified ISO 639-1 two-letter code?
Language names in the grid are as they appear in the Wikipedia list of ISO 639 language codes, including alternate English names but not endonyms. All normal JetPunk typeins are allowed.
As soon as one of the accepted language names is entered, the letters of all alternate names of the same language appear in the grid as solved.
