The process of somewhat losing grasp of your mother tongue or another familiar language due to a new language is a strange phenomenon. If you've gone through this, you’re not alone.

Those of you who have similarly based yourself in Germany over the past few years may know what I’m talking about when I say: the struggle is real when it comes to hanging on to your native language.

When I relocated here in 2012, I was as eager as ever when it came to learning German. Eventually when I could speak the language more or less fluently, it was a fulfilling feeling and I patted myself on the back for it.

Little did I know at this point though that soon afterward, the signs showing I couldn’t quite speak English properly anymore would creep up on me.

I had finally come to be able to chat with people at social gatherings as well as communicate with the authorities and doctors – but all of this came with a price.

Now and then, when chatting with family and friends back home, without even realizing it (complete with a big smile on my face) I’d start the conversation by saying “Naaaa?” This is despite the fact I was aware this term of endearment is virtually unknown to anyone who doesn’t speak German. Doh!

Similarly I’d find myself casually adding an “or?” at the end of sentences even while speaking English. This is likely because I had become so used to tacking on the German “oder?” at the end of sentences and my brain couldn’t adjust quickly enough.

Even nowadays I use German words (sometimes unwittingly) while speaking in my native tongue whenever the English word escapes me. The other day for instance when a colleague’s tire went flat I told him that his Schlauch was likely punctured or had a hole in it.

But these examples which show how German has messed up my English aren’t that bad in comparison with the times I really started to fear for the state of my first language.

From 2012 to 2015, my entire working life was devoted to teaching native German speakers and advising them on the English language. 

It was during this three-year period that I had the feeling my vocabulary was shrinking. I also felt like my ability to speak as eloquently as other English speakers was heading downhill.

Whether or not this was true, I’ll never know. What I know now though is that being surrounded by mainly native German speakers on a daily basis in some way or another affected my English.

This became especially evident when, ironically, I started to repeat the same mistakes I called my students out on. For instance, from time to time I myself would say uncommon or strange phrases like “in the near from” and “in former times” simply because my students said them so often and they were ingrained in my head.

“It’s inevitable that your English will be affected to some extent if you aren’t surrounded by the language on a day to day basis,” Ciaran Fleck, director of English studies at a Munich language school says.

Fleck adds that “odd German constructions” come out sometimes when he’s speaking English because his brain isn’t fast enough when it comes to switching between both German and English – the two languages he uses each day.

The Munich-based Irish national says he’s met English speakers who have been living in Germany for decades who legitimately “cannot go one sentence in their native tongue without Denglishing it.”

While I’ve never gotten to this point, after living in Deutschland for about five years, I wonder whether the “Anglophones” Fleck is referring to could have found ways to keep their native language up to speed. This is particularly interesting for me to consider since there's a chance I'll end up staying in Germany for the long haul.

When I stopped teaching in late 2015 and moved to Wales to begin a Masters programme, I noticed I gradually stopped using the strange phrases I’d picked up from my students. This led me to believe that one way of keeping hold of your English is to visit or spend some time in countries where it's widely spoken.

What’s also seemed to help me stay sharp in my mother tongue is reading. I found the more of the English language I consumed, the easier it was for me to remember words. Sooner or later I wasn't just retaining my English vocabulary, but also expanding it.

Making an effort to surround yourself and chat with native speakers may also be helpful to avoid getting to the point of unconsciously mashing up German and English in the same sentence.

This brings to mind something a friend of mine who’s a writer mentioned when we met for coffee the other day. She said despite the fact that she lives in Berlin (one of the only cities in Germany where you can get by without much German), she feels somehow at a disadvantage compared to writers in, say, New York City, since writers there are completely immersed in native-level English.

She added that although most days she's surrounded by the English language, it’s not necessarily mother tongue level; in an indirect sort of way this negatively affects her work.

I could empathize with how this could possibly be detrimental to her writing and personal development. Her situation does share similarities with what I'd experienced while teaching.

After I had a few moments to let what she said sink in, I told her she has something many of those writers in the Big Apple don’t have.

Her experience of living as a foreigner in a country where the local language isn’t her own gives her a unique perspective which can only make her writing stand out that much more. Her counterparts in NYC on the other hand don't have this perspective and never will.

Having lived now in Berlin for almost a year, I’ve seen for myself what I’d been hearing about the capital ever since I moved to Germany: people from all across the globe really do flock here. The common language for the majority of them is English, whether or not that's native level.

Personally though, I don't feel like my surroundings have influenced my first language in any way since I moved to Berlin. My year in the UK (which involved studying, writing and communicating completely in English) did wonders to get my mother tongue back in check and it's been smooth sailing since then.

Besides, Fleck doesn’t see being surrounded by non-native English speakers as necessarily a bad thing. “Adapting your English to those speakers will make you a competent communicator in an international environment,” he says.

This stands in stark contrast to a native English speaker who can’t grade their language appropriately, he adds.

With this in mind, I actually don't mind that German managed to fuddle up my English. And in future if I ever get to the point I was at a few years ago, I won't mind either. 

All it would mean is that I'd be challenged to communicate even more competently and I'd learn even more about the languages and cultures of those around me – neither of which is all that bad.
