This is why literacy is important. Being able to read the words helps to understand grammar and pronunciation. In fact, we can observe that dialects partly evolve from illiteracy, although to be clear, languages evolve anyway. In most countries the lower classes have more severe accents and dialects that deviate more from the standard of the language, because they are going totally by ear and also might be pulling from a first language, moreover if the community is fairly separated from the rest of society the dialect evolves separate from the rest of the society. I only mention all of this, because seeing the words written might be helpful and knowing the equivalents in Spanish. Having been is a past tense and describes having completed the action. I’m sure @Yeahright will know the exact type of past tense. So, what do I mean by completed the action. Here’s an example: Having been to Chicago, I know I don’t want to live there. Another example: I know to avoid the backroads having been there before. So, It’s something you experienced before and are no longer experiencing it. Being is happening now or in a continual state. He is being very nice. It’s understandably difficult. I am not sure of the correct Spanish to compare it to so I have to leave that up to the fluent speakers here. Edit: what I said about literacy is not a judgement about people who cannot read, it is simply an explanation that being able to read usually helps to learn a language or to pronounce a word. Take for instance y last name, most people cannot repeat it back to me correctly, but when they see it written and I say it at the same time, almost everyone has a quick click in their brain and never get it wrong again. There are exceptions in English since the spelling of so many words is unusual.
