In Arabic grammar, one of the clearest gender markers is the ‘ta marbuta’ (ة) ending, which typically signals a feminine form of a name — for example, Kareem (generous, masculine) becomes Kareema (generous, feminine) with this ending added. However, names like Noor (light), Iman (faith), and Islam (submission to Allah) are grammatically neutral Arabic nouns representing concepts or qualities rather than gendered forms, which is exactly why they’re used for both boys and girls depending on regional custom and family preference — there is no grammatical rule assigning them exclusively to one gender. For parents uncertain about a specific name’s grammatical gender, checking with an Arabic-literate scholar or a verified Islamic name resource that specifies the grammatical form is the most reliable approach.
