I have been interested in the study of language since I was a very young kid, and this caused me to give up everything else just to focus on the study of language. Applied linguistics has specifically been my passion and blessing, and every now and then I prepare a bibliography of research on applied linguistics for people who are interested in this very fascinating area. I have done a comprehensive search for the most trustworthy research studies conducted in this area in the first one-fifth of the 21st century which I present here to all of the interested people. This bibliography also includes a few to research studies from the 20th century, but its main focus is on the studies conducted between 2000 and 2020.
