If you speak Italian, some English grammar rules will feel natural and others will feel confusing. These are the biggest differences to focus on first.
Italian and English both use SVO order but Italian is more flexible. Adjectives come AFTER nouns in Italian most of the time โ 'una macchina rossa' means 'a car red'. English always puts adjectives before nouns.
Italian has gendered articles (il, la, lo, i, le, gli) that change based on the first letter of the following word. English articles never change based on what follows them.
Italian verb conjugations are more complex than English โ each person and tense has a unique ending. English verbs change very little by comparison. Italian speakers often find English verb forms surprisingly simple.
