Late Middle English (describing an art or occupation concerned with the design or construction of machines): via Latin from Greek mēkhanikos (see mechanic) + -al.

  • Both mechanical and machine (mid 16th century) go back to Greek mēkhanikē ‘machine’. Originally mechanical and mechanic (Late Middle English) were more or less interchangeable, but nowadays the first primarily means ‘operated by or relating to a machine’ or ‘done without thought, automatic’, and the second refers to a skilled worker. An old meaning of both is ‘a manual labourer or artisan’, as in ‘A crew of patches, rude mechanicals, / That work for bread, upon Athenian stalls’ from Shakespeare's A Midsummer Night's Dream (rude here meaning ‘unsophisticated’).
