In a shop today I discovered a charming little book, Other-Wordly: Words both Strange and Lovely from around the World by Yee-Lum Mak, illustrated by Kelsey Garrity-Riley.
Here are a few of their good words -
Brumous (adjective, English): of grey skies and winter days; filled with heavy clouds or fog; relating to winter or cold, sunless weather.
Nefelibata (noun, Spanish & Portuguese): "cloud-walker"; one who lives in the clouds of their own imagination or dreams, or one who does not obey the conventions of society, literature, or art.
Komorebi (noun, Japanese): the sunlight that filters through the leaves of the trees.
Psithurism (noun, English): the sound of the wind through the trees.
