I would like to ask about the function of 得 in this sentence:
我聽日仲有得面試添。
I understood the sentence as: "Tomorrow I still have an interview (additionally, on top of something else that might not have been mentioned)."
My question is why is there a "得"? I think the statement "我聽日仲有面試添。" without the "得" might have been perfectly fine?
得 here is part of an auxiliary verb: 有得 /冇得 in Cantonese.
有得 = (Mandarin: 能/ 可以) = able to (qualified to)/ can
冇得 = (Mandarin: 不能/ 不可以) = unable to (not qualified to)/ cannot
我聽日仲有面試添 = I also have an interview tomorrow (notice: 面試 here is a noun for "an interview")
我聽日有得面試添 I can (qualified to) do an interview tomorrow (notice: 面試 here is a verb for "to do an interview")
我聽日冇得面試 = I can't (not qualified to) do an interview tomorrow
More examples of 有得 /冇得:
考試合格有得去旅行 - pass the exam and you can go on the field trip
考試唔合格冇得去旅行 - fail the exam and you can't go on the field trip
六十五歲或以上有得攞養老金 - A person 65 years old or older can receive an old-age pension
六十五歲以下冇得攞養老金 - a person under 65 years old can't receive an old-age pension
Note:
In Mandarin, the auxiliary verb 得 means 要 = "have to; must" e.g. 我明天還得面試 (I still have to do an interview tomorrow).
Intuitively, I would say the two sentences are somewhat different in meaning. With 得 you frame the interview positively, so you could alternatively translate the sentence as "Tomorrow I still get to have an interview" which implies that you are happy to do the interview. Whereas without 得 you frame the interview neutrally/negatively, i.e. it could imply that you are not looking forward to the interview.
Example: 如果你坐定定，可能有得食糖啊！("If you sit still, you might get to have candy/a sweet!")
With 添 at the end, as you rightly mentioned, suggests the interview is additional on top of something else, so the sentence with 得 might imply that 'the other thing' is good, whereas without 得 might imply that it is not. However I'm not sure how these bits of colloquial language might be formalised in terms of linguistics/grammar terminology.
