If you speak Indonesian, some English grammar rules will feel natural and others will feel confusing. These are the biggest differences to focus on first.
Indonesian uses SVO order like English, making the transition fairly smooth for basic sentences. The main difference is that Indonesian is much more flexible about word order and can often omit subjects and objects when they are obvious from context.
Indonesian has no articles. Definiteness and quantity are shown through context, demonstratives, and number words. English articles must be learned as a new grammatical layer.
Indonesian verbs never change form. Affixes (prefixes and suffixes) add meaning โ like causative or passive โ but the verb root stays the same. English tense is expressed by changing the verb itself.
