muggy

adj

Etymology: From dialectal English mug (“fog, mist; Scotch mist”) + -y, ultimately from Old Norse mugga (“drizzle, mist”); borrowed some time before 1390, when a derived verb, Middle English mugen (“of a fog: to drizzle”), is attested.

1. Humid, or hot and humid.

   “The next was a very unpropitious morning for a journey—muggy, damp, and drizzly.”

   “What struck me as the most curious thing about this wonderful river was: how did the air keep fresh? It was muggy and thick, no doubt, but still not sufficiently so to render it bad or even remarkably unpleasant.”

2. Wet or mouldy.

   “muggy straw”

3. Drunk.
