What was the most difficult thing about learning to speak English?

I'm still in process of learning English for about 2 years now and the most difficult thing to learn is grammar and how to properly wright even understanding and spelling some words is so hard

English it is not very hard language to learn, I think one of the difficult points would be the idioms and words that are exclusive of a specific state.

Hello. I didn't learn English until I was 8. I'm now 20. I would say their most difficult thing about learning English was learning the phrases we say every day that don't really make sense. Such as "shut up". We know that means to be quiet. But growing up learning English I would ask, "why does that mean be quiet? Why not shut down?" It really doesn't make sense. or " he's bugging you" i thought that meant someone was throwing bugs on you. Lol little things like that made it hard for me to learn English. But their word structure and learning their English words themselves wasn't that hard.

The language itself is very easy, only the spelling is annoying and my pronunciation is not terrific, even now.

For different people it is different
