A nonnative speaker learning English would most likely struggle with which of these grammatical structures? subject/verb agreement
irregular verbs
present tense
subordination

irregular verbs

I think all the categories you have mentioned has its own importance on the particular area .If you want to learn English starts with basic stuffs like tense, sentences, irregular verbs and more importantly watch speeches of different people in English just to get the tone and rythym.

I also started by this way to be a good English speaker and try to find meaning of difficult and new words

I hope it helps and follow me for more good answers ♥️♥️
