Defuse and diffuse are a word pair of English language which are almost homophones, i.e. they have similar sounds but very different meanings and spellings. The massive differences in their meanings make defuse and diffuse unrelated and un-substitutable with each other.

Diffuse or defuse:

Diffusion is the opposite of “fusion,” which means a coming together of elements so diffusion is the spreading apart of elements. Defuse is the act of de-fusing i.e. removing a fuse from the bomb. Defuse is used when you are removing “de fuse” from an explosive situation—remove “de fuse.” Otherwise, it could blow up, and everything in sight would be diffused in an instant.
