from Battos (a proverbial stammerer) and 3056; TDNT - 1:597,103
AV - use vain repetitions 1; 1
1) to stammer
2) to repeat the same things over and over, to use many idle words, to babble, prate. Some suppose the word derived from Battus, a king of Cyrene, who is said to have stuttered; others from Battus, an author of tedious and wordy poems.
