Question

sort the words according to the meanings of their shared roots. posterior immortal postrevolutionary mortician mortal riposte after death

Explanation:

• For "after" category:
• The prefix "post - " means "after". In the word "posterior", "post - " indicates a position behind (after in a spatial sense related to position). In "postrevolutionary", "post - " means after the revolution.
• For "death" category:
• The root "mort" means "death". In "immortal", "im - " is a negative prefix, so it means not subject to death. In "mortician", it refers to a person dealing with the dead (related to death - handling). In "mortal", it means subject to death.

Answer:

• after: posterior, postrevolutionary
• death: immortal, mortician, mortal
