ludic

The word "ludic" is a direct borrowing from modern French ludique, which itself derives from the Latin noun ludus (a game, play, sport) and the related verb ludere (to play). The Latin root can be traced further back to the Proto-Indo-European (PIE) base leid- or loid-, which carried meanings related to playful activity, jesting, or even mockery. The suffix "-ic," of Greco-Latin origin, is a standard adjectival formant. Thus, the literal construction "pertaining to play" evolved in the mid-20th century to describe a specific psychological or behavioral quality of spontaneous, improvisational, and seemingly aimless playfulness, distinct from structured games.
