stirred up, be invigorated, flourish
奮 centers on a surge of energy that lifts someone into action: being stirred up, invigorated, or flourishing with renewed vigor.
奮 combines 奞 (a bird taking flight) with 田 (field), suggesting a bird bursting upward from a field—an image of sudden energetic movement.
Picture a large bird (奞) suddenly launching itself from a field (田), wings beating powerfully. That explosive takeoff captures being stirred up and invigorated.
For フン, imagine the fun of watching a bird burst into flight: fun -> フン, and the excitement makes you feel stirred up.
