destroy
剿 centers on forceful elimination: destroying or wiping out something completely.
剿 combines 巢 (nest) with 刂 (knife), suggesting the idea of cutting down or destroying a nest. The exact historical development is uncertain, but the component combination likely expresses wiping out or exterminating.
A knife 刂 is used to destroy a nest 巢, wiping out everything inside. This is total destruction.
For ソウ, imagine a saw cutting through a nest: saw -> ソウ, and the nest is destroyed.
