Late Middle English: from Latin implacabilis, from in- 'not' + placabilis (see placable).

  • please from Middle English:

    A word that comes via Old French plaisir ‘to please’ from Latin placere, found also in implacable (Late Middle English). Phrases like yes, please were originally short for ‘may it please you’ or ‘let it please you’. Please on its own, as used today, was not known to Shakespeare, who used please you: ‘Will you hear the letter?—So please you, for I never heard it yet’ (As You Like It). The proverbs you can't please everyone and little things please little minds are both old and can be traced back to the late 15th and late 16th centuries. Something pleasant (Middle English) was originally something ‘pleasing’, the meaning of the word in its French source. If you were complacent (mid 17th century) you were originally willing to go along with what pleases others.
