Often the words that were borrowed by Russian languages \u200b\u200bfrom others, are experiencing difficulties in adaptation. At the same time, the contradictions in writing or staging can last for a long time, and not even years, and in centuries. You can consider such a contradiction on a specific example. Do you know how the writing is correct: "tunnel" or "tunnel"?
The lexical meaning of the word tunnel (tunnel)
In itself, the word has a completely concrete value - this term is referred to as any designs created under the ground, or in the thicker of rocks, in order to lay the railway tracks, the road, or a passage pass or cyclists. This is the initial value and interpretation of the word.
Over time, other meanings began to appear. For example, in various subcultures of tunnels (tunnels), they call the artificially extended hole at the point of puncture in the ears, cheeks, lips, nose, intended for carrying piercing.
Also, the word tunnel (tunnel) is used in narrow specialty terminology, but here there is already a very definite value, and writing is also quite defined, for example, in such words such as tunneling or tunnel vision (syndrome).
How to write correctly: "tunnel" or "tunnel"?
In fact, with a rare exception, both writing options have a place to be, and whatever you choose, it will not be considered a mistake, even if you write a dictation and the author of the text is spelled out with a specific writing.
That is, writing a tunnel or tunnel, you will be right in both cases. Of course, if you take the historical component, then you can challenge this moment, however, once in Russian, the linguists were taken to write both versions of the word tunnel (tunnel), then it is not necessary to argue.
Onko should be remembered, in rare cases, in derivatives of the word tunnel used in the narrow industries of science or production, only the letter y, if you give an example, then in the same "tunneling" or in the "tunnel syndrome".
As for the double NN, in Russian, writing words tunnel (tunnel) always assumes that the NN will be double. Another writing option will be considered incorrect.
