His vocabulary is very poorly treated in the dictionaries; one of the many signs of the neglect into which he has fallen. There are at least twenty-four words in the Tractatus super Psalmos which are omitted in the last edition of Georges’ lexicon, and these good Latin words, not technical terms invented for purposes of argument. Among the most interesting is quotiensque for quotienscumque; an unnoticed use is the frequent cum quando for quandoquidem. Of Hilary’s other writings there is as yet no trustworthy text; from them the list of new words could at least be doubled.
