คือ
kʉʉ/kʰɯː˧/
The English phrase "is" can be translated into Thai as คือ (kʉʉ).
Use คือ when the sentence structure follows an "A is B" pattern, where B provides a definition or a specific identity for A.
Which one should you use?
The word คือ is used when "is" equates two things or defines something. In contrast, the word เป็น is used to describe a state or a role.
How does it change in a sentence?
The word คือ does not change based on the subject's number, person or tense.
How do you pronounce it?
The romanization is [kʉʉ].
What mistakes should you avoid?
English speakers often mistakenly use คือ to describe qualities, such as saying something "is tall". In Thai, adjectives are used directly without a verb like คือ.
Did you know?
- The word คือ is shared across a wide linguistic family, appearing as ຄື in Lao and គឺ in Khmer.
- Using คือ to describe a person's mood, such as 'He is happy', is a common error. To a native ear, it sounds as though you are trying to provide a dictionary definition of the person itself.
- In many Thai dialects, such as Isan or Northern Thai, a version of this word is used that is almost identical to the standard Central Thai คือ, reflecting a shared Tai-Kadai heritage.
