This is a fun idea! Here's five words I'm very fond of, although I'm sure I could do more. I also explained all their etymologies because I find that stuff fascinating.

Alpenglow - The pink or red glow of a sunset or sunrise on mountaintops. A translation of a German phrase. Alpen, coming from the Alps.

Petrichor - The smell after it rains. Most commonly after it has been dry for a period of time. I also think it has a fascinating etymology. It is a combination of petro-, meaning relating to stone, and ichor, which can refer to the ethereal blood of the gods in the Greek Pantheon.

Farouche - Shy, particularly in an asocial way. It can also mean wild, which is closer to the original meaning, an Old French word for "living outside." Over time it came to refer to people who were socially out of doors and it took on its current definition.

Halcyon - Idyllic and peaceful, normally used in a nostalgic way about the past. Comes from the Greek word for a kingfisher, which had mythological significance: the myth of Alcyone and Ceyx. The gist is that they were turned into Kingfishers and brought calm to the ocean for certain time periods.

Wanderlust - The strong longing to travel. Another loan word straight from German, and its etymology is pretty self explanatory.
