pre-existing
UK: ˌpriːɪɡˈzɪstɪŋ | US: ˌpriːɪɡˈzɪstɪŋ
adj. existing or occurring before something else in time or order.
The word "pre-existing" combines the Latin prefix "pre-" (meaning "before") with the verb "exist" (from Latin "existere," meaning "to stand out" or "to be"). The prefix "pre-" is widely used in English to indicate precedence in time or position. The root "exist" retains its original meaning of being or occurring. Together, "pre-existing" logically describes something that already exists prior to a specified point or event. This construction follows a clear pattern in English where prefixes modify root words to create nuanced temporal or relational meanings.
