suddenness, rise
勃 centers on something emerging or happening with sudden force: a sudden rise, a burst of energy, or an abrupt event.
勃 combines 孛 (historically associated with a comet or sudden appearance) and 力 (strength), suggesting a forceful, sudden rise or outburst.
The left side 孛 looks like a sprout bursting upward, and the right side 力 adds strength. Imagine a plant suddenly rising with explosive force.
For ボツ, picture a sudden burst of energy like a boat engine roaring to life: boat -> ボツ, and the boat surges forward abruptly.
