Hello- Asalam walakem (Note: this is similar to Arabic, but with a 'w'. This is a primarily Muslim country, so there are a lot of Arabic words and sayings that have crept into everyday language. N'shallah is another saying used often, meaning "god willing")
How are you? Tumi kamon acho?
I am good. Ami valo ache.
My name is Natalie. Amar nam natalie (or natalee, or natali, or natilee)
See you later. Abar dekha hobe.
I had bread (which is more like tortillas), eggs, and tea. A mi ruti, dim, abong cha keyechi.
What is happening? Ki hoche? (Note: I don't actually know what verb tense this is, but if I ask it, people tend to explain to me what is going on.)
I don't understand. Tumi ki bolcha ami bujhi nai.
No need-Lugbena (for example, when Kahala asks if she should bring me water to my room, I can say lugbena)
Too hot-koob gorom
(Note: both the words "brother" and "sister" are used before someone's name as a form of respect and politeness.)
Sit here- boukka (or in Sylhetti, Boso)
