Usage Tips
When using "普及," focus on the process or state of something becoming common or widespread. It is often paired with words indicating what is spreading (e.g., technology, ideas). Avoid confusing it with "拡散" which implies a more physical or rapid scattering. "普及" emphasizes gradual acceptance and adoption.
Common Mistake
Learners sometimes confuse "普及" with "普及率" (rate of spread). Remember that "普及" alone refers to the concept of spreading, while "普及率" quantifies how widespread something is.
