the/(one's) mother tongue(redirected from her mother tongue)
the/(one's) mother tongue
The native language of one's home country. I love coming to the area where all the expats live. Even though I am fluent in Japanese and love speaking it, it's nice to hear the mother tongue now and again. It's shameful how you have turned your back on your culture and heritage—your children don't even know their mother tongue!
