What does blithering mean?
Blithering is an informal adjective used as an emphatic intensifier meaning utter, complete, or total. It appears almost exclusively in disparaging contexts, most famously in the stock phrase 'a blithering idiot,' where it signals not merely foolishness but hopeless, incorrigible foolishness. A related use treats it as describing senseless chatter — 'blithering nonsense' — reflecting its origin in 'blither,' a variant of 'blather,' meaning to talk foolishly at length. The word is chiefly British in flavor, though it is well understood in American English, and it tends to lend a comic, faintly old-fashioned edge to an insult: calling someone a blithering fool sounds more exasperated than cruel. Because of this, it is popular in fiction, comedy, and everyday grumbling alike. For writers seeking a colorful alternative to plain intensifiers such as 'complete' or 'raving,' blithering offers a distinctive, memorable choice.
Utter or complete; used as an intensifier emphasizing total foolishness or senselessness.
"I felt like a blithering idiot after locking my keys inside the car twice in one week."
Almost always derogatory and informal; strongest in the fixed phrase 'a blithering idiot.'
Chattering or babbling foolishly; given to senseless talk.
"The meeting dissolved into blithering confusion as everyone talked over one another."
A less common, older sense closer to the original verbal meaning.
'Blithering idiot' may sound like a modern put-down, but the word descends from 'blather,' a Norse-rooted verb for mindless chatter that English has been mocking for centuries.

Etymology of blithering
Blithering derives from the verb 'to blither,' a variant of 'blather,' which entered English in the sixteenth century and traces back through Middle English to Old Norse 'blathra,' meaning to chatter senselessly. Cognates include the Scots form 'blether' and the related English words 'blabber' and 'babble,' all rooted in imitative syllables evoking meaningless talk. Over time 'blithering' shifted from describing foolish talk itself to serving as an intensifier meaning utterly foolish or nonsensical, a use now firmly established in British English.
