In this puzzle, solvers often encounter challenges when trying to categorize words that may fit into multiple groups. For instance, words like "urge" and "spur" might initially seem to belong in the same category due to their similar meanings related to encouragement. However, recognizing that they specifically relate to the prompt of encouraging actions with the phrase "on" is crucial to correctly grouping them under the yellow category. Another common point of confusion arises with items like "orange" and "mozzarella." While both can be considered foods, only "orange" fits into the spherical foods category, as mozzarella is not typically round in the same way. This can lead to misgrouping if solvers don't carefully consider the specific criteria for each category.

To effectively distinguish real groups from plausible decoys, solvers should focus on the defining characteristics of each category. In the yellow group, for example, all words must directly relate to the idea of encouraging with "on"—a specific action that narrows down options significantly. In contrast, the blue group is defined by grocery store aisles, which is a more straightforward classification based on common store layouts. By examining the context and specific clues tied to each group, solvers can eliminate words that don't fit, making it easier to identify the correct associations.

A useful heuristic for future puzzles is to always look for defining characteristics within the clues provided. For example, if a category hints at a specific phrase or action (like "with 'on'"), it’s essential to align words with that context. Additionally, considering the physical attributes of items, such as shape or common usage, can help when categorizing foods or products. By applying these strategies consistently, solvers can enhance their ability to quickly identify correct groupings and avoid common pitfalls.
