  Usage
  The verbs diffuse and defuse sound similar but have different meanings. Diffuse means ‘spread over a wide area’, while defuse means ‘reduce the danger or tension in’. Thus sentences such as Cooper successfully diffused the situation are wrong, while Cooper successfully defused the situation would be correct.
  Etymology
  ME: from L. diffus-, diffundere ‘pour out’; the adj. is via Fr. diffus or L. diffusus ‘extensive’.
