Saluton al ĉiuj.

Como novato que soy, quería preguntaros una duda que tengo que es la diferencia entre enen e internen, y entre enel y eksteren. No sé si será como en castellano la leve diferencia entre dentro, adentro, hacia adentro, etc., no lo sé, os agradecería mucho que alguien pudiera aclararlo.

I'm a beginner and I would like to know the difference between enen and internen, and between enel and eksteren. I just can't figure out the slight difference between them. Thank you very much for your help.

Multan dankon.

As far as I know enen and internen mean the same thing.
But don't quote me on that; I could be wrong.

I supose you mean elen. I am not completely sure of the difference, but I believe eksteren means to go outside or abroad, while elen is more vague just meaning to go outside (of something).

Someone else should way in though, because I am not sure.
