During the 8th and 9th emissions of Lugdunum under Probus the pietas reverse type was produced with two alternate spellings - PIETAS and PIAETAS. You will often see the PIAETAS coin sold as an error but it is more likely to be a spelling variation rather than an error. The PIAETAS spelling occurs over two issues and over multiple reverse dies and is generally as prolific as the PIETAS spelling variety. I have been gathering some of these over many years and have just tracked down a new addition to my collection, which gives me all the excuse I need to frag out some of my coins and share.... Just for the sake of this thread I will combine the obverse legend varieties separated by dots..... which Bastien gives a separate id but RIC does not.

This is strong evidence of linguistic change. In Lyon, by the reign of Probus, people apparently pronounced "pietas" with a diphthong: pee-ai-tas instead of pee-ay-tas.
