arpeti

From ar- +‎ séitid (“to blow”), possibly semantically arising from the use of oral literature and musical instruments for entertainment. The deuterotonic stem-initial p- is a back-formation from the lenited stem-initial -f- seen in prototonic forms. In this case, the -f- etymologically came from the lenition of the *sw- from Proto-Celtic *swizdeti, not a lenition of p-.
