Adventive

The term "adventive" can have different meanings depending on the context. Here are a few possible definitions:

In biology, an "adventive species" refers to a non-native species that has been introduced to a new area and has established a self-sustaining population. This is different from an invasive species, which not only establishes a population but also spreads rapidly and can cause harm to the environment, economy, or human health.

In linguistics, an "adventive word" is a word borrowed from another language and not fully assimilated into the recipient language's grammar or vocabulary. For example, the English word "cafeteria" comes from Spanish and still retains its foreign spelling and pronunciation.

In general usage, "adventive" can simply mean "coming from another place or source." For example, one might say that a particular idea or trend is adventive to a certain culture, meaning that it originated elsewhere and was imported or adopted by that culture.
