I'm trying to come up with a word meaning 'addition (before something)' in the sense: His title was 'holiness' but now it must be expressed with the ?something? 'supreme' (such that the title is now 'supreme holiness'). I want it to be clear that 'supreme' has to be added before the term 'holiness'. I thought perhaps 'superaddition', but that's somewhat different.
There might be a technical word that is specific for titles, but the word that seems to come most naturally is:
it must be prefixed with 'supreme'
it must be expressed [adorned?] with the 'supreme' prefix
The words prepended and adjoined also come to mind, but the first is mostly used in computer science, and the second connotes affixing more than prefixing.
