Left-side foot radical - the indexing radical.
止 originally pictured a foot planted on the ground (the toes splayed and a heel at the back). In
此 it depicts a person's foot stopped at a specific spot - 'right HERE, this place where I stand'. Same family of
止-based chars:
步 (walk),
武 (martial),
歧 (forked path),
正 (straight).
