'uniformly-approved' originates from the combination of 'uniformly' and 'approved'. 'Uniformly' comes from 'uniform', which originates from Latin 'uniformis', meaning 'having one form'. 'Approved' comes from Latin 'approbare', meaning 'to assent to'.

'uniformly' evolved from the Latin 'uniformis' through Old French 'uniforme', and 'approved' evolved from Latin 'approbare' through Old French 'aprover'.

Initially, 'uniformly' meant 'having one form', and 'approved' meant 'to assent to'. Over time, 'uniformly-approved' evolved to mean 'consistently accepted'.
