sow (female pig)
豝 refers specifically to a sow, a female pig. The meaning is narrow and concrete, with no broader conceptual cluster.
豝 combines 豕 (pig) with 巴, which likely serves as a phonetic component. The character is rare and its exact historical development is uncertain.
The left side 豕 is a pig, and the right side 巴 looks like a curled tail. Picture a sow with a distinctive curled tail to remember it means a female pig.
For ハ, imagine a sow laughing with a hearty 'ha!' as it rolls in the mud: ha -> ハ.
