esplanade: [17] Essentially, esplanade is the same word as explain, but whereas explain has lost its underlying literal meaning, esplanade has retained at least a memory of it. It comes ultimately from Latin explānāre, which meant ‘flatten out’, and so esplanade (acquired via French from the Spanish past participle esplanada) was originally simply a ‘large level area’. Its application to the ‘promenade’ at seaside towns is a comparatively recent development.
