For example, see this question: Through which language can you learn the most other languages?
That question mentions about Tagalog, Arabic and Tamil language. Now I don't want to disrespect any language, but it is the fact that those languages are not very popular, and I have no idea about them. I think in some situations, more information about them is helpful for readers who are not familiar with. Two examples of the information that I think it will be helpful are location of the country/area where the language is mostly speak and its relation to one of a popular language.
To ask in another way, my native language is Vietnamese. When I mention about it, is it more helpful if I add that Vietnam is a country in South East Asia, and 70% of its vocabulary borrowed from ancient Chinese?
What do you think?
