धुंध (dhundh)

noun A single-sense noun meaning 'fog, mist, or haze' -- both the literal weather phenomenon and, by extension, a hazy/unclear state of mind or vision.
Sense 1 : fog, mist, haze (literal weather)
noun, feminine
Synonyms: कुहासा (kuhaasaa), कोहरा (kohraa, more common for thick winter fog)
Frequency: high
Cultural Note: In Delhi-NCR, धुंध (dhundh) is a word you hear constantly in winter weather reports, often paired with प्रदूषण (pradooshan, pollution) since the city's winter haze is as much smog as mist. Newsreaders will say things like आज सुबह घनी धुंध रही (aaj subah ghanii dhundh rahii, 'there was thick haze this morning'), so this word is very much alive in daily life, not just poetic vocabulary.
Common Mistakes: 1) Learners sometimes use कोहरा (kohraa) and धुंध (dhundh) as if fully interchangeable; कोहरा (kohraa) usually implies a thicker, denser fog (common in North Indian winter mornings), while धुंध (dhundh) can describe a lighter haze, including pollution-haze, which does not need to be cold-weather fog.

Sense 2 : mental haze, confusion, unclear state of mind
noun, feminine
Synonyms: उलझन (uljhan, confusion, broader meaning), अस्पष्टता (aspashttaa, formal)
Frequency: medium
Cultural Note: Just as English speakers say 'my mind is foggy,' Hindi speakers extend धुंध (dhundh) to describe confused thinking or unclear memory, e.g. यादों पर धुंध छा गई (yaadon par dhundh chhaa gaii, 'a haze settled over the memories'). This figurative use often pairs with the verb छाना (chhaanaa, to spread/cover), the same verb used for literal fog spreading over a landscape.
Sample Sentences:
