What does aught mean?
Aught is an archaic English word meaning 'anything' or 'anything whatever.' Once a common pronoun throughout the language, it has largely fallen out of everyday speech, surviving today mainly in literary writing, in northern British and Scottish dialects, and in a handful of fossilized expressions — above all 'for aught I know,' meaning 'as far as I know' or 'possibly.' A sentence such as 'For aught I care, they may stay until midnight' shows its characteristic placement inside these fixed formulas. The word carries a distinctly formal, old-fashioned, even poetic connotation, which makes it useful when writers wish to lend their prose an elevated or historical flavor. Its natural opposite is 'naught,' meaning nothing, with which it shares ancient roots. Though rare in casual speech, aught remains fully understood by literate readers and offers a compact, evocative alternative to 'anything' when register calls for it.
pronounAnything whatever; a thing of any kind. In modern use it survives chiefly in literary, dialectal, and set expressions such as 'for aught I know.'
- Archaic or literary: anything at all; anything whatever.
- Chiefly Scottish and Northern English dialect: anything.
- In the fixed expression 'for aught I know': as far as I know; possibly.
"For aught I know, the letter may still be sitting unopened on his desk."
"She gave no sign that aught had changed between them."
"The old fisherman claimed he feared no storm, nor aught else upon the water."
'For aught I know' has survived for over a thousand years — aught comes straight from Old English and is one of the oldest words still hiding in everyday English idioms.

Etymology of aught
Aught descends directly from the Old English compound āwiht, formed from ā ('ever, aye') plus wiht ('thing, creature'), literally 'ever a thing' — hence 'anything at all.' Over the Middle English period the form shortened to aught. The same root element wiht also produced the words wight and whit, while the negative counterpart naught (from nāwiht) followed a parallel path and ultimately gave rise to modern 'not.' The word is thus native Germanic rather than borrowed.
How aught is actually used
Aught belongs to formal, literary, and archaic registers; in ordinary modern conversation 'anything' has almost entirely replaced it. It survives most naturally in fossilized phrases like 'for aught I know' and in regional dialects of northern England and Scotland. Writers sometimes revive it deliberately to evoke an older or more poetic style.
