Thayer's Greek Lexicon
Ἀββᾶ (WH (βά), Hebrew ΰΘα father, in the Chaldean emphatic state, ΰΗαΘΜΰ i. e. ὁ πατήρ, a customary title of god in prayer. Whenever it occurs in the N. T. (Mar_14:36; Rom_8:15; Gal_4:6) it has the greek interpretation subjoined to it; this is apparently to be explained by the fact that the Chaldee ΰΗαΘΜΰ, through frequent use in prayer, gradually acquired the nature of a most sacred proper name, to which the greek-speaking Jews added the appellative from their own tongue.
