What does blabbering mean?
'Blabbering' refers to talking at length in a rapid, continuous, and foolish or indiscreet way. It is most commonly encountered as the present participle of the verb 'blabber', though it can also function as a noun describing such talk itself. The word carries a distinctly negative connotation: someone who is blabbering is perceived as tiresome, silly, or unable to hold their tongue — particularly when they are revealing things better left unsaid. The term belongs to an informal register and appears frequently in casual conversation, fiction, and colloquial criticism ('stop blabbering!'). It is closely related to a family of expressive words — babble, jabber, gabble, prattle — all of which evoke speech that is either incoherent or excessive. What sets 'blabbering' apart from its near-synonyms is its emphasis on volume and indiscretion rather than incomprehensibility: the blabberer says too much, too freely, and usually to the wrong audience. The word is more common in American English than in British usage.

Etymology of blabbering
'Blabbering' derives from the verb 'blabber', an frequentative form of 'blab', which dates back to Middle English. The base word 'blab' originally meant to reveal secrets carelessly, and its reduplicated form 'blabber' intensified this sense into continuous foolish chatter. It belongs to a family of imitative or echoic English words for meaningless or excessive speech, including 'jabber', 'gabble', and 'babble'. The noun 'blabbermouth' emerged later as a colloquial term for someone prone to such talk.
