Morphology

Justinian + I

The phrase is simply the proper name 'Justinian' combined with the regnal numeral 'I' (meaning 'the first'), so a learner who knows 'Justinian' and recognizes the numeral usage will interpret it as 'Justinian the First, the Byzantine emperor'. The regnal-numeral pattern is cross-linguistically common and does not introduce an idiomatic meaning, making the construction directly compositional and understandable.

Etymology

Justinian I's name comes from an older word meaning 'just' or 'fair'. He was the emperor who gathered and wrote down Roman 'laws' into one big book, so you can remember him by the image of a ruler making the law clear and creating 'justice'.
