지 마세요/ 지 말고 = Do not…
This korean grammar point is used to persuide or order the listener to not do something, and comes after a verb. In English its exactly “do not”, however when we add “세요” giving you ~지 마세요, the enlish translation is exactly “please do not do….“. If this grammar point is used in formal speech we may use “지 마십시오“, which literally means “Please lets not do that” but it is used as “Please do not do it”. A very easy grammar point and it is used a lot.
