Words related to attrition
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 written forms in French were refashioned after Latin 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.

c. 1300, contrycyun, contricioun, "brokenness of spirit for having given offense, deep sorrow for sin or guilt with the purpose of not sinning again," from Old French contriciun "contrition, remorse;
a break, breach" (Modern French contrition) and directly from Late Latin contritionem (nominative contritio) "grief, contrition," noun of action from past-participle stem of conterere, literally "to grind" (see contrite). The modern sense is a figurative use in Christianity. The word was sometimes used in Middle English in the literal Latin sense "a crushing" (mid-14c.).
