Having the qualities of a gnomic statement; wise, pithy, and often expressed in an obscure or riddling manner.
From Greek 'gnōmikos' plus the English suffix '-al' (meaning 'relating to or characterized by'). This variant is less common than 'gnomic' but appears in older or more formal texts.
The existence of both 'gnomic' and 'gnomical' shows how English keeps extra adjective forms around like spare keys—sometimes we use them interchangeably, and no one minds.
