To talk rapidly, indistinctly, or foolishly, often making it hard for others to understand you.
Possibly from Dutch 'gabbelen' or related to the root 'gab.' The word emerged in English around the 16th-17th centuries to describe rapid, incomprehensible speech, often with onomatopoetic qualities suggesting the sound of rushed talking.
Gabble is wonderfully onomatopoetic—the hard 'g' sounds and the doubled 'b' actually sound like someone talking fast and jumbled, making the word mimic its own meaning!
