Yeah,Thank you.I love my own language more than others and I had a feeling like that.How would I say this to others in a polite way who is not my native language speaker?

Patriotism extends to language as well. It is a part of the culture and the attachment to their homeland. We can state that a person is linguistically patriotic, demonstrating national pride in their county's language. Similarly, we could define it in part nationalistic. I don't think we can separate the notion of language from culture; however, a love for a language would not necessarily be negative in a comparative fashion. We can view this in part as an extension of loving their heritage.

Hello! There isn’t a specific word in English that we use to describe a feeling a pride in your own native language. However, the word *chauvinism* could be used in such a circumstance. (Note that it is usually used in a negative light.) Chauvinism refers to extreme prejudiced support for some cause. So, linguistic chauvinism for language would be similar to patriotism for country. I hope this helps!
