Late 18th century: from French déployer, from Latin displicare and late Latin deplicare 'unfold or explain', from dis-, de- 'un-' + plicare 'to fold'. Compare with display.

  • display from Middle English:

    The early meaning of this was ‘unfurl (a banner or sail), unfold’. The word comes via Old French from Latin displicare ‘scatter, disperse’, which came to mean ‘unfold’ in medieval Latin and was also the source of deploy (late 18th century). In English the notion of ‘unfurling’ led to ‘causing to notice’. Splay (Middle English) was originally a shortening of display.
