What is your mother-tongue?
Can you actually define a mother-tongue?

According to the Collins dictionary; “Your mother-tongue is the language that you learn from your parents when you are a baby.”
Interesting, so in that case you can have two or even more mother-tongues, if you have parents from more than one country.
While the Oxford dictionary states that “the language that you first learn to speak when you are a child”. Again, that can definitely be more than one language then.
When I was growing up, my father, who was a professor of languages, stated that people tend to always count in their mother tongue. And if you do a search for that on Google, you also find that there is a lot of evidence that, indeed, people tend to count in their native language. Hmmm….
I grew up speaking Czech — till I was 8 years old. Though in my house Russian was also spoken, and I understood it — but did not learn to speak it. When I was 8, we became political refugees and the first country where we ended up was the USA. So, English became my next language and I am going to argue that it became my “mother tongue”. After a couple of years in the USA, we moved to the Netherlands, and I learned Dutch. Now in my retirement, I live in France and speak — more or less — French. But for the biggest part of my life, I lived and worked in England.
So which language do I count it? Nearly always English. Which language do I think in? Nearly always English. And I dream in English too. Unless I am actually speaking Czech, Dutch or French at that moment, I will always revert to English. If I am speaking one of the other languages, then I may count (even just in my thoughts) in the particular language I am speaking. I will also think in that language. But the moment I stop, and I am quietly on my own I will revert to English.
So, has English become my mother tongue — even if it wasn’t the language I learned as a child? Even though I didn’t even speak it before the age of about eight. And then how many people are out there like me who do not count or think in their mother-tongue? And does that then change what your mother-tongue is and how coded it is in your brain?
Any linguists out here that will want to answer this? (I can’t ask my dad anymore…)
Or even who else on this world-wide Medium platform has come across this? It will be interesting to see.
