What's the difference between diffuse and scatter?

Diffuse


Definition:

  • (v. t.) To pour out and cause to spread, as a fluid; to cause to flow on all sides; to send out, or extend, in all directions; to spread; to circulate; to disseminate; to scatter; as to diffuse information.
  • (v. i.) To pass by spreading every way, to diffuse itself.

Scatter


Definition:

  • (v. t.) To strew about; to sprinkle around; to throw down loosely; to deposit or place here and there, esp. in an open or sparse order.
  • (v. t.) To cause to separate in different directions; to reduce from a close or compact to a loose or broken order; to dissipate; to disperse.
  • (v. t.) Hence, to frustrate, disappoint, and overthrow; as, to scatter hopes, plans, or the like.
  • (v. i.) To be dispersed or dissipated; to disperse or separate; as, clouds scatter after a storm.
