Interesting things about learning Vietnamese.

1. Vietnamese has many consonants

A Vietnamese word can mean something like this, or something else, for example, "đá" can be both a noun and a verb, stone can mean "ice" and "kick". In general, Vietnamese has a lot of consonants, and if used incorrectly, it can be confusing

2. Written Vietnamese 

Vietnamese is not the only stigmatized language, but the stigmatic combination of Vietnamese makes a very good tone and sounds like singing, even if it's just reading. 

3. Vietnamese has one word, but it replaces many other words.

It is the word "ấy", the word "ấy" can replace the previous phrase mentioned for example "that person", "that day". Even this word can stand alone in writing. 

4. There are more and more new words in Vietnamese. 

Usually, Vietnamese will produce some new vocabulary over time and as more people use it will begin to become more common, so sometimes you may hear some new words spoken by Vietnamese but textbooks are not available. For example, the word "flirt" means "thả thính" or the word "xà lơ" means "lie".
