English is actually quite easy. Yes, there is a lot of vocabulary, but almost no conjugations or declinations make it easy compared to some others. My native has 19 different cases with 2-3 variants each for tonal coherence, and 2 modes of full verb conjugation (with additional exceptions of course).
What i found very difficult in english is the fact that there's no rule on how to pronounce words; you have to learn how to pronounce each word individually. which means that you might know how a word is written and what it means while not being able to recognize it when listening to someone speaking in english.
