Cantonese phrases you will hear people say to you:
Yau mo gao chor
- Are you for real? -OR- Can't believe him/her/you! When you are running
for a bus and knock someone's head with your 40 pound backpack, you will hear
that from your victim!
Chee sin - crazy!
M T Arlo - MTR (the subway)
K C Arlo - KCR
(the train that goes north into the New Territories)
Cantonese phrases you can say to people:
Mmm Goy - Yap, you have to pronounce the "Mmm"! It means "no". The
two sounds put together means "thank you". Literally you are saying to people "you
shouldn't do that for me" - a courteous phrase. But you say this only when someone
does something for you, or in asking someone to do something for you. To thank
someone for giving you something, for instance, a gift, you say "dor
je", which is explained next.
Dor je
- this means "thanks". Literally it means "many thanks". But you only say this
when thanking someone for giving you a gift, not for doing something for you.
Ho ho sigg - this
means "it tastes good" or "they taste good". Literally it means "good good eat".
But then of course with this phrase, you can easily get the tones wrong and it
becomes "like (fond of) women very much" - with negative connotations - since Cantonese
is a tonal language!
Chee
Saw - this may prove to be the most useful Cantonese phrase you can
learn: bathroom! |
