es‧pla‧nade, n. /ˈɛspləˌnɑd/
From the Spanish word for “to explain,” esplanar. An esplanade was a field from which philosophers and professor would explain their theories and discovereies. Additionally, before the great mystery novels were translated to have “parlor room scenes,” such scenes would take place on an esplanade. It is believed this was originally for ironic purposes.
