The abundant usage of particles in conversation is one of the most distinctive features of Singapore linguistic culture. It is typical for the conversations of Singaporeans to be littered with particles, whether they are speaking in English or Mandarin. These particles are loaded with pragmatic meanings. Many studies have been carried out throughout the years to explicate the meanings and functions they carry. However, the usage of such particles in conversation often makes no sense to foreigners.

Moreover, most studies have investigated the usage of particles in the context of Singapore English (Singlish) conversation, but are oblivious to the fact that the phenomenon is equally significant in Singapore Mandarin conversation.

This study looks at the particle leh in Singapore Mandarin conversation. Its aim is to investigate the inherent meaning of leh within the Natural Semantic Metalanguage (NSM) framework, as well as the functions that come with the different lexical tones of leh, using data from natural conversation. Lastly, the phonetic changes of leh in Singapore Mandarin are also examined.
