Where does “alma” come from?

I need to carefully analyze this etymology chain, but I notice a significant problem: the chain provided doesn't actually support "alma" as an English word derived from these Arabic and Proto-Semitic roots. The chain shows: - Arabic عَالِمَة (ʿālima) - Arabic عَلِمَ (ʿalima) - Arabic ل (l) - Proto-Semitic walad- The Proto-Semitic "walad-" means "child/boy," and the Arabic forms relate to "knowledge/learning" - neither connects to "alma." I cannot write an accurate etymology sentence because: 1. The chain doesn't credibly trace "alma" to these roots 2. The meaning is marked unknown 3. The connection between Proto-Semitic walad- and the Arabic عَلِمَ forms is unexplained 4
