Innocent of wrongdoing; not deserving criticism or responsibility for something bad or unfortunate.
From Middle English, combining 'blame' (from Old French 'blasmer', ultimately from Greek 'blasphemein' meaning to speak ill) with '-less' indicating absence.
Interestingly, 'blame' shares its root with 'blasphemy', showing how accusations of wrongdoing and religious offense were historically linked - both involve speaking against someone or something, whether human or divine.
