In anatomy, which prefix denotes the left side?

Explanation:
Understanding how directional prefixes work is essential. In anatomy, the left side is indicated by the combining form sinistr/o-, which comes from the Latin word sinister meaning left. This forms terms describing left-sided structures or orientation, such as sinistral for left-sided. In contrast, trans- means across, post- means after or behind, and sub- means under, so these do not denote left. Therefore, sinistr/o- is the prefix that denotes the left side.
