display: [14] Display originally meant ‘unfold’, and it is related not to modern English play but to ply. It comes via Old French despleier (whose modern French descendant, déployer, is the source of English deploy [18]) from Latin displicāre. This was a compound verb formed from the prefix dis- ‘un-’ and plicāre ‘fold’ (source of or related to English accomplish, complicated, ply, and simple), and in classical Latin seems only to have had the metaphorical meaning ‘scatter’.
In medieval Latin, however, it returned to its underlying literal sense ‘unfold’, which was originally retained in English, particularly with reference to sails or flags. The notion of ‘spreading out’ is retained in splay, which was formed by lopping off the first syllable of display in the 14th century. => accomplish, complicate, deploy, ply, simple
