...English is not spectacularly hard, but the grammar can still be difficult for those who do not speak a fellow Germanic language. It has no grammatical gender and has very regular plural-marking. The hard part of English grammar is the Germanic Strong Verbs (sing-sang-sung, get-got-gotten, etc.), the great complexity in verb forms (such as "I was going to have been being stopped", where "was" indicates past tense, "going to" indicating the Intentional Mood, "have" indicating Perfect aspect, "been" indicating Progressive aspect, and "being" indicating the Passive Voice.), and the phrasal verbs (put on, put off, take out, blow off, got on, got off, got after, etc. But English's grammar is still much more reasonable to the complicated and irregular declensions and conjugations of Latin, Greek, Sanskrit, Lithuanian, Russian, and other conservative Indo-European languages; or the 3-consonant-root system of the Semitic languages such as Arabic and Hebrew, or the Noun Classes of the Bantu languages like Zulu and Swahili, or the extreme agglutination found in Chechen or Ojibwe.
