plead: [13] Essentially plead and plea are the same word. Both go back ultimately to Latin placitum ‘something pleasant’, hence ‘something that pleases both sides’, ‘something agreed upon’, and finally ‘opinion, decision’. This was a noun formed from the past participle of placēre ‘please’ (source of English please). It passed into Old French as plaid ‘agreement, discussion, lawsuit’, and formed the basis of a verb plaidier, from which (via Anglo-Norman pleder) English got plead. In later Old French plaid became plait, and Anglo-Norman took it over as plai or ple – whence English plea [13].
