To chatter, to clack Dr Pusey thinks it is derived from Paternoster (the Lord's Prayer) The priest recited it in a low, mumbling voice till he came to the words, “and lead us not into temptation,” which he spoke aloud, and the choir responded, “but deliver us from evil ” In our reformed Prayer Book, the priest is directed to say the whole prayer “with a loud voice ” Probably the “pattering of rain”- i e the rain coming with its pit-pat, is after all the better derivation Gipsy talk is so called from the French patois (See Patavinity )
