Forego/Forgo
If you skip dessert, will you forego or forgo it?
Forego is to precede or come before.
Forgo (without an “e”) is to do without.
The introductory paragraph should forego the body of your essay.
I decided to forgo buying a new car in order to save money.
In most cases, the intended word is probably forgo, but the “e” is inserted, resulting in a spelling error. (Forego is not as commonly used.)
