'stadium-esque' is a modern English coinage combining the noun 'stadium' and the suffix '-esque' (from French '-esque'), used to form adjectives meaning 'in the style of' or 'resembling'. 「stadium（スタジアム）」とフランス語由来の接尾辞「-esque（〜風）」を結合した現代英語の造語です。

'stadium' itself comes from Latin 'stadium' via Greek 'stadion' (meaning a measured course or racecourse); the suffix '-esque' entered English from French '-esque', which came from Italian '-esco' and ultimately from Late Latin/Latin formations. The compound 'stadium-esque' arose by productive modern use of '-esque' to make adjectives from nouns.

The formation originally means 'in the manner or style of a stadium' and has retained that compositional meaning, applied metaphorically to design, atmosphere, scale, or form.
