the verb 'waffle', meaning to speak or act indecisively, originated in british english in the late 17th century. it evolved from the now-obsolete dialect verb 'waff', which meant to yelp or bark like a small dog, a word of onomatopoeic origin mimicking a yapping sound. the connection lies in the idea of making inconsequential, repetitive noise. the '-le' suffix, often used to form frequentative verbs (denoting repeated action), transformed 'waff' into 'waffle', emphasizing the repetitive, vacillating nature of the speech or behavior. the modern sense of speaking evasively or being unable to decide solidified by the late 19th century, capturing the essence of verbal or mental back-and-forth motion.
