Negate is defined as to deny, to prove false or to cause something to not be needed. 1  An example of to negate is to conduct a study to prove a theory false. 2  An example of to negate is for an umbrella to take away the need for a hood.
In symbolic terms, you negate a statement by sticking in front of it (putting the whole statement in brackets if it is complicated enough to need it). You can then read as ânotâ, or if you want to be absolutely sure you are getting the meaning right, as âit is not the case thatâ.
