In《命中注定我爱你》when someone calls out 陈欣怡's name, why does she reply 有?
有 http://www.cantonese.sheik.co.uk/dictionary/characters/128/


有

/jau5/ /jau6 /  (jyutping)

/you3/ /you4/   (pinyin)

[粵] jau5 | [國] you3


1 [v] have; own; possess | [ant] 冇
[2] [v] there is; exist; be present


[粵] jau6 | [國] you4


[adv] variant of 又 (e.g. 二十有六)


When she said "有够平凡" (very ordinary), '有够'(have enough) means  非常/真的(very/really)

She yelled "有!"(present!) When people was calling her. Which means "I'm Here!"
