Definition of invasive

The word "invasive" originated in the 15th century from the Latin words "in" meaning "into" and "vasivus" meaning "pertaining to a vessel". Initially, an invasive species referred to a plant or animal that grew or spread into a new area or soil, often displacing native species. Over time, the term's meaning expanded to include the concept of a foreign species invading and dominating new habitats. In the 20th century, the term took on a broader meaning, encompassing not only biological but also social and human contexts. Today, an invasive technology, idea, or behavior refers to something that rapidly gains popularity or spreads rapidly, often overwhelming established norms or systems. Despite the shared noun, the original biological context and the modern sociocultural usage of the word "invasive" share a common thread: the idea of something encroaching on and changing an existing environment.
