corona
ES [koˈɾona] · Spanish for “crown” · matches Czech koruna (a crown)
To a Czech, koruna is money - the coins and notes you hand over every day. So it is a small jolt to learn that Spanish corona is the literal crown the currency was named after in the first place. Same word, one resting on a head and one folded in a wallet.
Both descend from Latin corona, a wreath or crown (itself from Greek korone, a curved garland). Spanish kept corona; Czech took koruna, which doubles as the name of the currency - crowns jingle in a lot of pockets, from the Czech koruna to the Swedish krona and Danish krone. The shape hides in plain sight elsewhere too: the Sun's corona is its crown of light, a coronation sets the crown in place, and the coronavirus is named for the ring of crown-like spikes around it. English crown is the same word, worn down through Old French. One Latin wreath, resting on heads, coins, stars and viruses alike.
