Relating to or characteristic of a czarina or the rule of a female czar.
Formed from czarina with the adjectival suffix -ian, parallel to how we get Italian from Italy or Hungarian from Hungary, allowing for description of things related to female czarist rule.
This word is rarely used despite being grammatically logical, which suggests that English speakers didn't often need to specifically discuss 'czarina-related' things separately from general czar topics—a gap in our vocabulary that shows what historical topics mattered most to English speakers at different times.
