That's daft. Imagine the amount of misunderstandings.
Daft but true. Similar scope for misunderstandings in Vietnamese too.
Each word has six meanings depending on the tone. If you say 'grapefruit' wrong, you say 'cock'. Say 'big' wrong, you say 'c**t'. Say the boy's name 'Hiep' wrong, 'rape'. The name 'Vu,' Boobies.
Tonal languages are a minefield!
