Da is a word used in Ireland,mainly the dublin area and it is short way of saying dad.
'Da', in street language, is the principle definite article and equivalent to 'the' in more formal English.
The use of the the /d/ derives from two main aspects:
-to add emphasis on a phrase
-quicker and easier to ignore the 'th' sound, usually for non-native English speakers (such phenomena is prominent in the word 'ting' rather than 'thing.')
Other variations of this include:
-dis (this)
-dat (that)
Person 1: Who did dat?
Person 2: Da person over der.

Varations: daa, dah, doy, a-da, a-doy, da-ah
These varations were all very popular in the 70's. "Da", with a short "a", was originally pronounced in a brief, crisp, insulting manner. The more recent "Valley" pronounciation, "Da-ah", beginning sometime in the 80's draws out the short "a" into almost questioning tone.
