What does delimitating mean?
"Delimitating" is the present participle of the verb "delimitate," which means to fix, mark, or establish the boundaries or limits of something — whether a physical border between territories, the scope of a research project, or the extent of a legal authority. The word derives ultimately from the Latin "limes" (boundary) combined with the prefix "de-", and it belongs to the same family as "limit" and "delineate." In practice, "delimitating" is uncommon: the standard English verb is simply "delimit," so most editors and style guides prefer "delimiting" over "delimitating." Where it does appear, it is typically in formal legal, academic, or technical prose concerned with precisely drawing lines — literal or figurative. Writers should be aware that choosing "delimitating" may read as verbose or even erroneous to careful readers.

Etymology of delimitating
"Delimitating" comes from the verb "delimitate," formed from the prefix "de-" plus "limitate," rooted in the Latin noun "limes" (genitive "limitis"), meaning a boundary or limit. The underlying notion of fixing boundaries passed into English through Medieval Latin "delimitare." It shares this Latin root with "limit," "limitation," and "delimitation." The simpler form "delimit" arose earlier and remains the dominant verb in modern English.
