purple group · The short answer
PRIME ___
Each puzzle word passes the same exact test. The four mappings show how the answer works.
A PRIME NUMBER is a whole number greater than one with exactly two positive divisors.
PRIME REAL ESTATE means especially desirable land or property in a favorable location.
PRIME RIB is a familiar name for a particular beef roast or serving cut.
PRIME TIME is the period when a broadcast audience is expected to be especially large.
Why this group was difficult
- The shared word is not on the board
Solvers must infer PRIME as the missing preceding word instead of matching the four entries by a direct definition. - The expressions span unrelated subjects
The resulting phrases concern mathematics, property, food, and broadcasting, so their surface meanings provide little unity. - Some completions feel more familiar than others
PRIME NUMBER and PRIME TIME are immediate, while PRIME REAL ESTATE and PRIME RIB require checking the complete pattern.
How to spot this pattern next time
When two entries accept the same preceding word, search the board for two more complete and familiar expressions using that exact construction.
Test PRIME before NUMBER and TIME, then verify the less obvious completions PRIME REAL ESTATE and PRIME RIB.
Four useful facts behind the group
- A prime number has exactly two positive divisors.
- Prime real estate describes especially desirable property.
- Prime rib is a well-known beef roast.
- Prime time refers to a high-audience broadcasting period.
