Difficulty: MediumPrefix and Suffix Analysis

Match each vocabulary word containing key prefixes and suffixes on the left to its most accurate synonym on the right based on morphological analysis.

  • CircumspectPrudent
  • DispassionateImpartial
  • ImmutableUnchangeable
  • RetroactiveBackdated

Answer

Circumspect pairs with Prudent; Dispassionate pairs with Impartial; Immutable pairs with Unchangeable; Retroactive pairs with Backdated.
Each word's precise meaning is determined by its constituent affixes and root: "Circumspect" means looking around prudently, "Dispassionate" means without bias or passion (impartial), "Immutable" means not capable of change (unchangeable), and "Retroactive" means acting backward in time (backdated).

Step-by-Step Solution

1
Analyze the word parts of "Circumspect".
The prefix "circum-" signifies "around" and the root "spect" means "to look or observe."
A word meaning "looking around with caution" corresponds directly to "Prudent".
2
Analyze the word parts of "Dispassionate".
The negative prefix "dis-" indicates "without or free from," modifying "passion."
Operating without emotional bias or personal passion describes being "Impartial".
3
Analyze the word parts of "Immutable".
The prefix "im-" indicates negation, "mut" relates to change, and "-able" indicates capacity.
An adjective describing something that cannot undergo change matches "Unchangeable".
4
Analyze the word parts of "Retroactive".
The prefix "retro-" denotes "backward in time," combined with "act" and suffix "-ive."
An action or measure taking effect prior to its creation matches "Backdated".
