Good evening and welcome to Word of the Day! A journey through the English vocabulary and the words that piqued my interest, in WotD we'll be learning a new word for each working day of the week, bar holidays, unless there's a holiday special...

Today's word is:

plenipotentiary

|ˌplenəpəˈten sh ēˌerē; -ˈten sh ərē|

noun ( pl. -aries)

  • A person, esp. a diplomat, invested with the full power of independent action on behalf of their government, typically in a foreign country.

adjective

  • Having full power to take independent action : [ postpositive ] he represented the Japanese government in Seoul as minister plenipotentiary.
  • (of power) absolute.

ORIGIN: mid 17th cent.: from medieval Latin plenipotentiarius, from plenus 'full' + potentia 'power.'

Plenipotentiary... a more complicated way of saying ambassador. From my point of view the word bears a more powerful and dominant aura compared to it's synonym, and the origin explains very well how the word is formed ^^;
