boar
猪 centers on the wild boar, a strong, untamed animal. The meaning is straightforward and specific to this creature.
猪 combines the animal radical 犭 (beast) with 者, which likely contributes the sound. The character specifically denotes a wild boar.
The left side 犭 is a wild animal, and the right side 者 looks like a person with a hat. Imagine a wild boar charging at a person, who throws their hat in the air in surprise.
For チョ, picture a wild boar charging at you, and you shout 'Cho!' in surprise. The short, sharp sound 'Cho' matches the reading チョ.
