répandus
Répandus is not a standard modern French term. In most contemporary contexts, répandu serves as the correct past participle of répandre (to spread or scatter). The form répendus appears occasionally in Latinized or archaic spellings or in stylized titles and scholarly writing, where -us is a common masculine singular ending in Latin or in Latin-derived variants. Because répandu is the usual French form, répandus has no stable, widely recognized meaning in everyday usage.
In practice, when répandus is encountered, it is typically interpreted as a Latinized adjective or participle
Away from Latinized contexts, writers will normally prefer répandu or other synonyms such as dispersé or diffusé.
