Relating to or composed of a group of one thousand; pertaining to thousands or a chiliad.
From 'chiliad' (a thousand) + '-al' (a suffix forming adjectives). The base 'chiliad' comes from Greek 'khiliás' (thousand), with '-al' being a common English adjectival suffix from Latin.
This ultra-rare adjective demonstrates how English can theoretically form words for any concept through morphology, but in practice, we rarely say 'chiliadal' when 'thousand-fold' or 'thousandfold' works better—showing the difference between possible words and actual language use.
