What did AHang say to Ri'Muê

A’Hang 阿杭 said to Ri’Muê 二妹:

Ua2 dêng2 li7 lai5 cuê7 le2

我等哩來覓汝

And in Mandarin: 我等一下就來找你

I will come and find you in a little while.

 I would say:

Ua2 ka2dêng2 lai5 cuê7 le2

我敲等來覓汝

I come and find you afterwards.

And Ri’Muê replied:

Ho2 ua2 do6 zi2lai6 dêng2 le2

好我在只內等汝

In Mandarin: 行我在家裡等你

Alright, I will wait for you at home.

I wonder when did the dang2 [to wait] become dêng2? AND you will even hear some people saying 待 tai6 to mean wait!
