The word of the day on lexico.com is "
cark".
That one you find in Spenser a lot. He seems to have liked the way it sounded. I rather do myself.
Here's a nifty one I just caught in RV VI.65 (to Dawn). The S ऊ॑र्म्या
úrmyá (acute = macron, fucking Chromebook) is a word for 'night' that ostensibly means 'wavy' (from ऊर्मि
úrmi) and may well be an ellipsis because the 'standard' word for 'night' is feminine (and naturally so is the goddess).
A perceived likeness, and later equation, of the nighttime sky to the ocean may explain the old god Varuna's being relegated from horrible, all-seeing, all-judging overbearing Uranus archetype to the more mundane, capricious & stormy but not almighty Poseidon.
Incidentally, I remember that the Ancient Hebrew words for 'water' and 'sky' were (supposed to be) cognate, although they may have been synchronically remodeled (folk analogy).
