I was writing in Latin recently and was remarking to myself how strange "proh dolor" looks. It seems odd to see a Latin word ending in "h," and a Perseus search for such words reveals (beside Semitic loanwords) only the following exclamations:
I have two questions about these words.
- Where does this "h" come from?
- Do we have any indication of how it was pronounced? My own practice is simply to ignore it, e.g. pronouncing "proh" like "pro."
