Relating to or suitable for displaying or showing something in public.
From exhibition (Latin exhibitio, 'a showing forth') + -al (adjective suffix). The suffix -al was added to the noun exhibition to create an adjective form.
This word is quite rare—most English speakers use 'exhibition' as an adjective directly (like 'exhibition match') rather than adding -al, showing how adjective formation isn't always predictable.
