"أَهْلاً يا جودي."

Translation: Hello, Judy.

Why the يا ?

[ConchiCastillo]

Someone has already explained the use of this particle, but since I can't find the relevant post, here is what Wikipedia says about it:

يَا • (yā)

vocative particle preceding a noun used in direct address; only rarely omitted in such contexts; occasionally translated as o or hey
يا كندا!‎
yā kanadā!
O Canada!
يا كريم...‎
yā karīm...
(Hey) Kareem, ...
يا حبيبي!‎
yā ḥabībī
Hey my love!

[leinaduo]

You use it every time you are speaking with someone and you call them by their name. It's a vocative particle.
