‘Trump’ is a little bit tricky for Indonesians for two reasons:
Indonesians will use sounds that are close enough for the sake of communication, and when they say ‘Donald Tram’, we know they mean ‘Donald Trump’. But if you’re taking IELTS you can easily score points for pronunciation by producing the correct sounds:
The phoneme /ʌ/ is very common in spoken English: up, under, mother, thorough, etc.
Finding spoken examples of ‘Trump‘ should be easy – just switch on CNN! (And remember to switch on your ears, too!)
BTW in British English, ‘trump’ is a slang word for ‘fart’! 🙂
