In this case, the accent on "ár" needs to be taken into account.

ár = slaughter

"do t[h]abairt méla fort" is a nominal phrase, centered on the verbal 
noun "tabairt", meaning "to bring shame on you", and the whole phrase 
beginning "in fer" and ending with "fort" is thus a noun phrase (at 
least in my mind!)
