I request the language teaching experts and researchers to suggest me the possible sources to apply for external funding. It can even be collaborated or interdisciplinary projects as well. Thanks in advance.
IMHO, the bigger question is what your research field / topic is. For example, you are more likely to get funding if you are connecting English language and I.T. in your research proposals.
Also, I think it fundamentally depends on the country you wish to work in as there are several country-specific programs available. And I agree with Locky Law that you should be a bit more precise when it comes to the project you are interested in working in.
