Ah Sir

Here I cover two bits of vocabulary.

There are at least two ways to address a male teacher in Cantonese:

• Ah sir - this is from the English Sir.
  
• [sin] saang - this can be used for teacher (male or female), Mr. or husband

A female teacher can also be Me si. Thai thai (or just thai) is Cantonese for Mrs. or wife. Lo pau is another word for wife (lo means old). Lo kung is another word for husband.

The word Hai has 6 meanings, they are is; am; are; in; at; yes. Nghoh hai Shan means I am Shan and it is how you would introduce yourself.
