In the "maiN/meN" thread, Faylasoof SaaHib in passing mentioned these two verbs and I quote the relevant part of his post. I am aware of the existence of these two verbs but I must confess I have always thought of them as synonymous, both meaning "to swim" and "to float". In speech and writing I have come across "tairnaa" as the much more commoner verb. My first choice of usage would be "tairnaa" and that is simply because I have n't been exposed to "pairnaa" that much. I would like to know from forum friends if they see these verbs as distinct or synonymous. Would you prefer the choice of one over the other in your day to day speech?
