purple group · The short answer
LOW LANDFORMS WITH A LETTER CHANGED
Each puzzle word passes the same exact test. The four mappings show how the answer works.
Change the second N in CANNON to Y to form CANYON, a deep lowland passage with steep sides.
Change the F in FORGE to G to form GORGE, a narrow valley or passage with steep sides.
Change the C in RACINE to V to form RAVINE, a deep narrow hollow or valley formed by erosion.
Change the O in VOLLEY to A to form VALLEY, a low area of land between hills or mountains.
Why this group was difficult
- The answers are not visible as written
None of the four board entries directly names the landform; the intended terms emerge only after a one-letter substitution. - The source words have unrelated meanings
CANNON, FORGE, RACINE and VOLLEY point toward weapons, metalwork, a proper name, or sports before their spellings are altered. - The letter changes are not uniform
Each word changes a different letter and into a different low-landform term, so the pattern is structural rather than phonetic.
How to spot this pattern next time
When four leftovers seem unrelated, compare each spelling with familiar geographic terms using exactly one letter substitution.
Confirm the transformed words as a set: CANYON, GORGE, RAVINE, and VALLEY must all be low landforms.
Four useful facts behind the group
- A canyon is a deep valley with steep sides.
- A gorge is a narrow passage or valley with steep sides.
- A ravine is a deep, narrow hollow often shaped by erosion.
- A valley is a low area between hills or mountains.
Questions players ask
The details people search after seeing the group
How do CANNON, FORGE, RACINE and VOLLEY connect?
Changing one letter in each produces CANYON, GORGE, RAVINE and VALLEY, all terms for low landforms.
Which letter changes CANNON into CANYON?
The second N changes to Y, leaving CANYON as the resulting low-landform word.
Why is VOLLEY in the purple group?
Changing its O to A creates VALLEY, so its spelling rather than its sports meaning supplies the connection.
