Other forms: dissuaded, dissuading, dissuades
To dissuade somebody is to talk them out of doing something. Reasons, warnings, and eventually a change of mind.
It takes from and usually a verb after it: dissuade him from going, dissuade her from selling. The word is formal and it is the exact opposite of persuade, which makes the pair easy to learn together. Note that dissuading is about talk, so an obstacle does not dissuade you, it deters you. It very often appears in the negative, since nothing could dissuade him is a standard way of showing determination.
