Usage notes
- For geometric or circular distance, use raggio; for a broad area of action, Italian often prefers area rather than raggio.
- In light contexts, raggio is common; fascio suggests a concentrated beam, while bagliore means glow, not a ray.
- For wheel parts, raggio is the spoke. Learners may confuse it with razza, which means breed or race.
