In your opinion, what is the most common learning languages difficulty for all new language learners?

Learners usually have difficulty in the speaking area as , unfortunately, most of the teaching methodologies focus on writing and grammar and give little attention to speaking. 

From the learner's side, finding the right people to practice the language with could also be a difficulty. To master a language, learners have to surround themselves with it as much as possible. They have to practice it it different contexts and situations. Socialization has to be great. 

Grammar, Lexics and finally, the usage - fluent and correct speaking in this new language 

If it really not your national language it is difficult to learn special the same spelling but different pronunciations and meaning and how you will use it to communicate with other person most dificult language i think is speaking in german or african tribe languages

I always study languages ​​on my own, as it is more comfortable for me than studying with a teacher.

The Grammer and the fluency of new language which can be overcomed only with practice
