Etymology

Derived from Latin "posterus" (coming after), "posterior" combines "post-" (after) with the comparative suffix "-erior," akin to "-er" in English (e.g., "greater"). The term originally denoted spatial or temporal sequence in Latin, later adopted into English (16th century) for anatomical and hierarchical contexts. The root "post-" persists in words like "postpone" (put after) and "postscript" (written after).
