The first definition you provided is correct. When something is described as "endemic," it means that it is native to a certain country or area. It refers to the natural occurrence or prevalence of a particular species, characteristic, disease, or phenomenon limited to a specific region. It can be used to describe plants, animals, cultures, traditions, languages, or diseases that are specific to a particular place and not found elsewhere.
The correct definition of "endemic" is that something is native to a certain country or area. It refers to a species or disease that is regularly found and restricted to that particular region. It is not related to being weak or ineffective by nature. Instead, it implies that the thing being described is specifically and uniquely characteristic of that specific place.
