Here are some examples:
* "The researcher delimited the study to participants between the ages of 18 and 25." This means the researcher set a boundary on the participants who would be included in the study.
* "The treaty delimited the border between the two countries." This means the treaty defined the exact line that separates the two countries.
* "Please delimit your presentation to the key findings of the research." This means to focus the presentation on the most important parts of the research and not go into unnecessary detail.
In short, "delimit" is about setting clear boundaries and defining limits to ensure clarity and focus.
