Question for introverts: do you think it has an effect on your language learning?

No, because 1) my focus is on reading and writing, anyway and 2) I'm not shy, I'm just an introvert. If speaking was my goal, I think my inability to do things typically extroverted when it comes to language learning would have more to do with lack of options in my location and a little bit of, "I'm not paying for that."

Sometimes, I really struggle to speak with people, even on the internet. I didn't feel that feeling before, but now, I've some problems talking with strangers.

Absolutely it does. More extroverted people naturally talk more in social situations, and talking is arguably the biggest part of communicating in a new language. It is possible to get as much practice as an introvert, but in larger groups, extroverts will usually have more speaking practice.

Some people report different social personalities for themselves in different languages. It can help you realize the connection between being shy and having insecurity. Also, I've read a linguist who swears by rehearsing conversations in the shower as a fantastic help to learning other languages. 

Yes.

No effect for me learning Spanish, I don’t think. Then again, I am an introvert but NOT shy. They are not the same thing. I think shyness / social phobia can be quite a problem. A lot of posts on various subs and forums are basically “how can I learn a language without talking to anyone?”

Fun fact about that. While the etymology of *bigote* and *bigot* are both partially unknown, they are thought to have come from the same concept, but from different folks in different times. The word bigot goes back to the early medieval period when the French would call the Normans *bigot* (which meant religious hypocrite) because they would go around saying *"bi God"* which was Middle English for "*by God*" (as the Normans occupied England after 1066). The word bigote in Spanish (and bigode in Portuguese) is thought to come from Middle High German "*bi Got*" which also means "*by God*" and might have come from the mustaches worn by Landsknecht mercenaries.

I don’t think so. I’m an introvert so I spend most of my time reading, consuming media while I paint, or learning more about my profession, programming, which happens to be primarily taught and discussed in English. I’m also not anti social or shy, so I’ve never had any problem speaking in English or initiating interactions with English-speaking individuals; I don’t really mind making mistakes or getting corrected, I in fact asked my friends to tell me if they notice me consistently make the same mistakes. I think where I struggle the most is with writing, as I don’t enjoy texting much and I’m far more capable of expressing my thoughts and ideas in my native tongue so I rely on it more to journal or draft projects.

For the first few years of learning English in a classroom setting I had the worst fear of verbal communication. We'd take turns speaking sentences, even if it was as simple as reading off of a book, I'd freak out. I still did it but I hated it. I think I was just insecure in my accent, but I do consider myself an introvert overall. The point is, it deterred me from practicing as much as I could've. This resulted in my speaking evolving considerably slower than my reading comprehension, writing, grammar etc.

Because of my interest in etymology and language history, I know the basics of various languages but most of them I haven't developed past that, and the ones I can communicate in I rarely do even if there's an opportunity for it, because I am too critical of my accent, even if it sounds fine to the other person. I find learning dead languages to be more my thing because there's no expectation to have to speak them because no native speakers exist. I think being able to overcome that is the biggest thing, but for me even if I know someone doesn't care about my accent it doesn't change anything. It doesn't help that when I moved between states in the US my accent was found to be amusing to the people I worked with to the point it impacted everything I said because people were listening to how I said things and not what I said. And that was the same language. I ended up adopting a more neutral American accent (like a TV news anchor accent) to avoid that.

Yes, I'm like B1 in French but being too anxious to do anything like italki makes it harder to progress
