blame

\ \ [12] Blame and blaspheme are ultimately the same word. Both come from Greek blasphēmein ‘say profane things about’, but whereas blaspheme has stuck to the path of ‘profanity’, blame has developed the more down-to-earth sense ‘reproach, censure’. The radical change of form seems to have come via blastēmāre, a demotic offshoot of late Latin blasphēmāre, which passed into Old French as blasmer, later blamer (whence English blame).
