proliferre
Proliferre is a nonstandard spelling that may appear as a non-diacritic rendering of the French verb proliférer, which means to proliferate or to increase rapidly in numbers or extent. The infinitive form is proliférer; the standard present tense forms include je prolifère, tu prolifères, il prolifère, nous proliférons, vous proliférez, ils prolifèrent. The non-accented form proliférer or prolifère may appear in older texts, in data exports that strip diacritics, or in contexts where character encoding prevents accented characters. In contemporary French, the form prolifère with the acute accent on é is the correct third-person present.
The verb proliférer is commonly used in biology, epidemiology, and social science to describe rapid growth
