Etymology
'Anno' originates from Latin, specifically the word 'anno' (ablative form of 'annus'), where 'annus' meant 'year'.
'Anno' passed from Classical Latin (ablative/dating form of 'annus') into Medieval Latin usage (e.g. 'Anno Domini') and was adopted into English in fixed dating phrases; the form and use have remained largely formulaic in dating contexts.
Initially it meant simply 'in the year' (the ablative/dating form of 'annus'), and over time it has been preserved mainly in set phrases (such as 'Anno Domini') to indicate calendar years.
