Proliferaste

Proliferaste is the second-person singular pretérito indefinido (simple past) form of the Spanish verb proliferar. It means you proliferated, i.e., you multiplied or spread rapidly. Proliferar comes from Latin proliferare, widely used to express rapid increase or expansion in both biological and figurative senses.

As a regular -ar verb, proliferaste follows the standard pretérito indefinido conjugation: yo proliferé, tú proliferaste, él/ella/usted proliferó; nosotros proliferamos, vosotros proliferasteis, ellos/ellas/ustedes proliferaron.

Usage notes: The form is used to attribute a past action of multiplication or spread to the familiar you in informal contexts. It frequently appears in narratives, scientific discussions about cell division or population growth, and in journalism or prose describing rapid dissemination of information, rumors, or trends. In scientific writing, proliferar is more commonly described in third person (las células proliferaron), but tú proliferaste may appear in first-person narratives or quoted speech.

Limitations and nuances: Proliferar is often intransitive in its core biological sense (to proliferate), though it can take objects in figurative or extended usage. When writing about growth or spread initiated by a person, the phrasing may require rephrasing to maintain natural fluency, especially in formal or academic contexts.
