rudėnja

 roo-DAY-nyah

 The way nature begins to feel as autumn takes hold and the vestiges of summer disappear. Not the season itself but its emotional and sensory quality — the cooling, the dimming, the withdrawal.
Etymology
 Lithuanian. A word that names a transition rather than a state, and a felt quality rather than a measurable one.
Notes
 Already entered in the untranslatable words section. Flagging it here as a seasonal term as well.
