leur

Etymology
, from, from , genitive masculine plural of.

As a possessive it was originally uninflected (as still is 🇨🇬), but adopted the plural ending in Middle French. Feminine was hindered by the analogy of other possessives, all of which have but one plural form and in the case of  no gender agreement at all.
