Perhaps instead of thinking about each language as separate systems on their own, it might be better to think of each as simply a part of the entirety of knowledge, as every one of them containing a piece of Truth.
Just like how there are philosophical concepts I have yet to understand or literary tropes I have yet to read, there are also linguistic symbolisms I have not yet learned to decipher and ways of forming sounds my tongue and ears are yet to be familiar with. However, just because I am at the present unable to do so does not mean I never will, nor does it mean that they are truly something foreign or something separate from me.
A child may not yet understand algebra in their first year of schooling, but that does not mean algebraic equations are beyond their means.
In the same way, not being able to read another culture’s language does not mean that it cannot be an intrinsic part of that person the same way their mother tongue is.
Thinking about it further, someone’s first language is greatly a matter of circumstances. One with a certain ethnicity may be born far from where their ancestors were from and consequently learned a “foreign” mother tongue. Such person may still learn to speak in the same tongue as their ancestors just as how someone completely “foreign”—meaning with absolutely no direct connection—can learn that tongue all while in a different continent from a person of another nationality.
And so, the next time the ‘Translate this’ button appears, try looking at the unfamiliar scribbles and reflecting whether something within, something that runs deeper than formal knowledge or social exposure, can feel a more natural connection to it. One may not be able to immediately understand it in its fullest, but the same can still be true toward the alphabet one had grown up with, right? All the words may look familiar but it is not impossible for its meaning to still remain hidden.
And yet all of that, whether comprehensible or not, are held together by one thing that roots all humans alike. Maybe that is our ‘shared humanity’ but what does that even mean? Maybe it is the Truth, with a capital first letter. Maybe, maybe…
