'consistently-enforced' originates from Modern English as a compound of 'consistently' and 'enforced'. 'consistently' ultimately comes from Latin, specifically the word 'consistere', where 'con-' meant 'together' and 'sistere' meant 'to stand'. 'enforced' comes via Old French 'enforcier' from Latin-rooted 'force' (from Latin 'fortis' meaning 'strong').

'consistently' developed from Latin 'consistere' through Medieval and Middle English forms such as 'consistent' and then the adverbial suffix '-ly' to become 'consistently'. 'enforced' evolved from Old French 'enforcier' and Middle English 'enforcen' to the modern English verb 'enforce' and its past participle 'enforced'. The compound adjective 'consistently-enforced' is a modern English formation joining the adverb and past participle.

Initially, the roots of 'consistently' related to 'standing together' and 'enforce' related to 'making strong' or 'compel'. Over time these developed into 'doing something in the same/regular way' (consistent) and 'to impose or compel compliance' (enforce). Together they now mean 'imposed in a uniform, steady manner'.
