When is a degree required? or: hai6 vs hou2 vs gei
ngo5 hai6 baau2


--> 我係飽 is "unnatural", hmmm, non-native way to express.


  ngo5 hou2 baau2


--> 我好飽

native way to say it :)

just like the english "being", in other language, the verb changes:

i'm 70 years old 

(being is used to describe age), which is translated to:

j'ai 70 ans

(avoir [to have], is used, not être [to be]; then, in cantonese, it should be:

我七十歲

technically, the verb is omitted


  gei(unsure of tone or meaning) 


it is 嘅(u+5605), roughly "my, his, her, their"; ask you friend how to pronounce it ;-)

last, i would suggest learning cantonese from dramas, videos, and news, forget grammar books.

have fun :)
