The difference between "delimit" and "limit"

Delimiting something is different from limiting it. To delimit is to to mark the limits or boundaries of something; to limit is to restrict, and not to allow to go beyond certain bounds. That is, delimiting entails finding out and setting forth existing limits; limiting entails enforcing bounds.

Delimit - To define a boundary for something.

Limit - Already defined boundary for something.

Take a case when you are defining some new rule, and you are going to set some boundaries/restrictions in it/to it. Then you can say it as DELIMITATION but once the rules are defined and boundaries are set, then rule is said to be in/with some LIMITS.

This is what , i know the difference between the two from best of my knowledge...

To limit looks to me something that is more likely to apply to a single axis and a single direction, i.e. to set or observe a point/measurement that you cannot our should not cross. To limit defines what is below vs what is beyond.

On the other hand, to delimit would be something that apply to a surface or a volume. To delimit defines what is inside vs what is outside.
