Many English words have different meanings depending on which context they are used in, therefore enabling a person with not so vast a vocabulary range to express themselves in many ways. That is an advantage. But just tell me one thing: What about all the effort you have to go through to memorise all these different meanings?
I believe that it is your perseverence and how hard you apply yourself when studying another language that makes that language seems easier or more difficult. It depends on how much time you spend listening , speaking, reading and writing in that language and how curious you are to find out things you are not sure of.
Of course, it does help if the language you are studying is similar to your own in some way. Every language has its peculiarities and also easy and difficult features…!
