lallation

She spoke Aramaic with a lazy lallation, affected by many because it was the natural speech of a class.

When you talke with your children you expect from them no congruence or quaint language, yet you are often pleased to heare them prattle, & are delighted with their lisping Ideoms. This makes me hope that you will dispence with the Lallation & Low dialect of this babe, whose tone is rude, yet his meaning is plaine dealing, which according to the proverbe is a jewell, and consequently most fit for Ladies.
