attribution n.

word-forming element expressing direction toward or in addition to, from Latin ad "to, toward" in space or time; "with regard to, in relation to," as a prefix, sometimes merely emphatic, from PIE root *ad- "to, near, at."

Simplified to a- before sc-, sp- and st-; modified to ac- before many consonants and then re-spelled af-, ag-, al-, etc., in conformity with the following consonant (as in affection, aggression). Also compare ap- (1).

In Old French, reduced to a- in all cases (an evolution already underway in Merovingian Latin), but French refashioned its written forms on the Latin model in 14c., and English did likewise 15c. in words it had picked up from Old French. In many cases pronunciation followed the shift.

Over-correction at the end of the Middle Ages in French and then English "restored" the -d- or a doubled consonant to some words that never had it (accursed, afford). The process went further in England than in France (where the vernacular sometimes resisted the pedantic), resulting in English adjourn, advance, address, advertisement (Modern French ajourner, avancer, adresser, avertissement). In modern word-formation sometimes ad- and ab- are regarded as opposites, but this was not in classical Latin.

mid-14c., "stated sum of money or other valuable consideration paid by one ruler or country to another in acknowledgment of submission or as the price of peace or protection," from Anglo-French tribute, Old French tribut and directly from Latin tributum "tribute, a stated payment, a thing contributed or paid," noun use of neuter of tributus, past participle of tribuere "to pay, assign, grant," also "allot among the tribes or to a tribe," from tribus (see tribe). Sense of "offering, gift, token" is first recorded 1580s.

"attribution (of a work of art or literature) to the wrong person," 1865, from mis- (1) "bad, wrong" + attribution. Related: Misattribute; misattributed; misattributing.
